Background
Today's electronic technology is constantly moving towards more intelligence and humanization. The device designed based on the traditional electronic technology has the defects of poor deformation capability, easy brittle failure, extremely poor fit with organism tissues and the like, so that the device is difficult to meet higher requirements of people. However, the appearance of flexible electronic technology is breaking through the stiff of electronic technology development, and the core idea is to integrate a high-performance circuit with a flexible substrate, so that an electronic device has the characteristics of large deformation, light weight, reconfigurable function and the like.
The electronic device has flexibility by adopting the combined design of the inorganic film and the flexible substrate, and is a technology realized earlier in the technical field of flexible electronics. Bending deformation is therefore one of the most fundamental and important deformation capabilities in flexible electronics. The amount of device bendability is often scaled by the minimum radius of curvature that the device can withstand, with smaller radii indicating greater bendability.
In addition, for a typical flexible electronic system design, several different materials are combined in the same platform, so the flexible electronic device is generally a multilayer structure formed by compounding a plurality of thin films and a substrate. When flexible devices or structures are subjected to frequent bending or stretching, cracks are easily generated for harder materials, and severe stress concentrations are easily generated at hard/soft interfaces, thereby easily causing delamination and separation of layers with mismatched mechanical properties. In the structural design, the thin film layer which is easy to damage is arranged at the position of the neutral layer, and the thin film layers can be well protected. Therefore, it is very important to know the bending deformation capability boundary of the flexible multilayer structure, but the bending deformation capability of the flexible multilayer structure is detected by an actual test, so that the method is not accurate and effective enough, and has high cost and low detection efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for simulating deformability of a flexible multi-layer structure according to an embodiment of the invention.
In this embodiment, the method for simulating deformability of a flexible multilayer structure includes:
Illustratively, a corresponding planar geometric model of the flexible multilayer structure is established in the simulation system.
Specifically, the simulation system may employ ABAQUS simulation software.
ABAQUS is a powerful finite element software for engineering simulation, which solves problems ranging from relatively simple linear analysis to many complex non-linear problems. ABAQUS includes a rich library of cells that can simulate arbitrary geometries. The ABAQUS can not only solve a large number of structural (stress/displacement) problems, but also simulate a plurality of problems in other engineering fields, such as heat conduction, mass diffusion, thermoelectric coupling analysis, acoustic analysis, geomechanical analysis (fluid permeation/stress coupling analysis) and piezoelectric medium analysis.
It will be appreciated that the structural properties of the layers of the planar geometric model are arranged to match the characteristics of the actual flexible multilayer structure.
It can be understood that the flexible multi-layer structure needs to be attached to a carrier when being bent and deformed, so that a carrier model is established to simulate the state of the flexible multi-layer structure when being bent and deformed.
And step 130, obtaining a deformation model of the plane geometric model attached to the carrier model.
Illustratively, the bending deformation condition of the plane geometric model attached on the carrier model is observed and calculated, and a deformation model is obtained, so as to simulate the deformation capability of the flexible multilayer structure.
According to the flexible multilayer structure deformability simulation method, a plane geometric model of the flexible multilayer structure is established; setting the structural attribute of the plane geometric model; establishing a carrier model; the method for obtaining the deformation model of the plane geometric model attached to the carrier model simulates the flexible multilayer structure, and enables the plane geometric model of the flexible multilayer structure to be in contact with the carrier model in simulation so as to calculate the deformation model of the flexible multilayer structure, so that the calculation is accurate and effective, the cost is reduced, and the detection efficiency is improved.
In another embodiment, creating the planar geometric model of the flexible multilayer structure comprises creating the planar geometric model based on in-plane geometric characteristics of the flexible multilayer structure or simplifying a three-dimensional model of the flexible multilayer structure to obtain the planar geometric model. It can be understood that when the plane geometric model is directly established according to the actual flexible multilayer structure, the dimension in the thickness direction can be ignored, and only the corresponding plane geometric model is established according to the in-plane geometric characteristics of the flexible multilayer structure. When the original geometric model is imported by external software, operations such as mid-plane extraction and Boolean operation can be adopted to simplify the three-dimensional model of the flexible multilayer structure so as to obtain the planar geometric model.
Referring to fig. 2 and 3, fig. 2 and 3 are schematic diagrams illustrating a flexible multi-layer structure simplified from a three-dimensional model to a planar geometric model according to an embodiment of the invention.
In another embodiment, setting the structural properties of the planar geometric model includes setting one or more structural properties of region selection, material setting, thickness, and reference plane corners of the planar geometric model. Specifically, in the ABAQUS simulation software, Composite Layups (Composite stack) setup is performed in the Part subcommand of the planar geometric model. The number of Plies (number of layers) corresponding to the actual number of layers of the multilayer structure is set, for example, if the multilayer flexible structure is a 3-layer structure model, and the number of layers 1, 2 and 3 is from bottom to top, the number of Plies needs to be set to be 3. For each Ply, the structural properties that have to be carried out are set of the choice of the area (Region), the material (Materials), the Thickness (Thickness) and the Angle of reference (Rotation Angle). The region selection is set by selecting a figure corresponding to each layer in a planar model of the multilayer structure; the setting of material properties and thickness is determined according to an actual model; the angle of rotation of the reference surface is typically set to 0 degrees; and setting other parameters by default setting of simulation software. In addition, sometimes it is necessary to set the Reference plane and its offset (Shell Reference surfaces and Offsets), if pieces are arranged in the bottom-up order, the offset mode should select the bottom Surface option, otherwise, the top Surface option.
In another embodiment, modeling the carrier includes modeling a cylindrical rigid rod carrier. Specifically, according to the calculation requirement, a discrete rigid body type or an analytic rigid body type is selected, and a plurality of cylindrical structures with different radiuses are established to be used as a carrier for attaching the flexible multilayer structure. It can be understood that the plurality of carrier models with different radii are established to enable the corresponding plane geometric model of the flexible multilayer structure to be attached to the carrier models with different radii, so as to test the range of bending and deforming capabilities of the flexible multilayer structure.
Referring to fig. 4, fig. 4 is a schematic diagram of a cylindrical rigid rod carrier model for analyzing rigid bodies and discrete rigid bodies according to an embodiment of the present invention, where the left side of fig. 4 is a schematic diagram of a cylindrical rigid rod carrier model for analyzing rigid bodies, and the right side of fig. 4 is a schematic diagram of a cylindrical rigid rod carrier model for discrete rigid bodies.
Illustratively, obtaining the deformation model with the plane geometric model attached to the carrier model comprises taking the bottom surface of the plane geometric model as a slave surface and the surface of the carrier model as a main surface, and enabling the plane geometric model to be in contact with the carrier model, specifically enabling the plane geometric model to be in tangential frictionless surface-surface contact with the carrier model. Specifically, a deformation model of the plane geometric model attached to the carrier model is obtained by a dynamic method or a static method. It can be understood that, in general, a statics method is selected for solving, and if the statics method is not converged in calculation, a dynamics method can be adopted for solving again. The setting of boundary conditions for rigid cylinders is a uniformly fixable mode, i.e. setting the reference point of a rigid body and applying full constraints to it. However, for the flexible multilayer structure, the application manner of the boundary condition is not uniformly fixed, and can be set according to actual requirements.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a contact between a plane geometric model and a carrier model according to an embodiment of the invention.
Referring to fig. 6 and 7, fig. 6 and 7 are schematic diagrams illustrating a simulation of the deformation capability of the flexible multi-layer structure according to an embodiment of the present invention, that is, a plane geometric model of the flexible multi-layer structure is attached to a carrier model, and the bending degree and the deformation effect of the plane geometric model in the attached state are calculated, so as to obtain the deformation capability of the flexible multi-layer structure.
Referring to table 1, table 1 shows a method for applying boundary conditions for bending analysis of a square-shaped flexible multilayer structure.

It can be understood that the bending deformation capability of the flexible multilayer structure can be obtained by calculating the deformation field of the plane geometric model attached to the carrier model by a dynamic method or a static method.
