Application and research of numerical simulation for rubber like material with MSC.Marc
Because there are varieties of the strain energy functions of rubber like material, implementation of these models in a general finite element program to meet the need of industry applications can be time consuming. In order to make use of the constitutive equation of Gao model 3 and make computational analysis of the static behavior of rubber like material, a framework to implement the rubber-like material model is established within the general-purpose finite element program MSC.Marc. It will be very facilitatory to implement this isotropic hyperelastic model into the program with a user subroutine. This paper starts with a discussion on the theory of finite deformation and various types strain energy functions of rubber like material, the material parameter of elastic law of Gao3 is estimated by experiment and numerical simulation. Because there are various types of strain energy functions, a user subroutine is programmed to implement the strain energy function of Gao3 into the program of MSC.Marc, which offers a convenient method to analyze the stress and strain of rubber-like material with the strain energy function that is needed. Two examples will be presented in this paper to demonstrate the use of the framework for rubber like materials. One is to simulate a foam tube in compression. The other one is to simulate a rectangle board with a circular hole. After numerical analysis, it is proved the numerical results based on Gao model are in perfect agreement with the results based on Mooney model and the estimated material parameters are valid.
