The Study on the Mechanical Properties of Closed-Cell Foam Rubber Based on Microstructure Model

Abstract:

This paper analyses the mechanical behavior of matrix material and cell structure of closed-cell foam rubber by Gibson-Ashby model and the strain energy function of incompressible rubber-like material. The constitutive relation of closed-cell foam rubber is established by the overlay analysis of the two impact factors. The constitutive data for the new model is fitted and the uniaxial compression experiment is utilized to prove the feasibility of the constitutive equation produced in this paper. The model is in good agreement with the experimental results.
