Polycarbonate Substrate

Thin metal films on polymeric materials have been widely used in electronic devices. Their total mechanical performance is determined by the mechanical property of each material, the thickness and size of film and substrate, their interface properties in addition to the temperature change during production and use. In this paper, stress and strain distribution of gold thin film on polycarbonate substrate subjected to tension and cooling was analyzed using the finite element method. The effect of cracking in thin film on the stress and strain distribution was also discussed.

Stress And Strain Distribution

A certain thickness of two, three and four layers of axisymmetric finite element bellows model were built by Abaqus firstly. Then the axial stiffness and stress and strain distribution of multi U-shaped bellows were simulated by finite element analysis. The results showed that in the case of a constant thickness, with the increase of the number of layers of the bellows, the stiffness of the bellows would be significantly reduced, and in the case of large deformation, the overall stiffness of the bellows would change significantly and was divided into elastic stiffness and plastic stiffness.

Stress And Strain Distribution

Three-dimensional integrated modeling method and the numerical simulation of elastoplastic finite element are adopted in the paper. The mechanical response of the five holes anchorage is analyzed in certain prestressed state. The stress and strain distribution information of the anchor ring, clip and steel strand is obtained respectively, and the structure safety is discussed by investigating on the maximum stress and strain.

Stress And Strain Distribution

This article established 3D FE model of dual-radius arc finishing groove and tangent expansion angle finishing groove using ANSYS / LS-DYNA software for Wuhan Iron and Steel plant Ф16 hot continuous bar, and analyzed metal flow pattern, stress and strain distribution of two types finishing grooves. The results show that surface stress and strain distribution of dual-radius arc finishing groove have better uniform than them of tangent expansion angle finishing groove, and dual-radius arc finishing groove ensures the stability of the rolled piece in finishing groove, improve the dimensional accuracy and surface quality of rolled finishing product.
