In this article, we are introducing a new analysis tool to identify material constants of viscoelastic problems.
Abstract: In recent years, we have been receiving an increasing number of inquiries regarding analyses that consider the nonlinear behavior of materials such as resins. We believe that the purpose behind this is to use CAE to examine the application of new materials and the high demand to improve long-term reliability, which is triggered by the need to realize a sustainable society. However, it is also true that the use of CAE for nonlinear problems can present some stumbling blocks in the early stages of the analysis study, the best example being the preparation of material property values. Although there are established methods for experimentally obtained material behavior, especially for viscoelastic problems, and CAE software has provided such analysis functions for a long time, the curve fitting function for obtaining physical property values have certain challenges.
To solve these problems, we have developed a tool to identify the physical properties of viscoelastic materials in a versatile and easy way with the cooperation of Nihon University. This article presents an overview of its functionality.
