Creep Analysis of Polymer Matrix Composites by Finite Element Method Based on the Shift Factors Method

Abstract

Creep is one of important properties of polymer matrix composites (PMC).It can be analysis by finite element method (FEM).But creep will be affected by a lot of factors and the creep material parameters are very difficult to be obtained. Shift factors method is one simple method which can be used to obtain the creep properties by fewer tests. Here the basic method analysis of the creep of PMC by FEM was studied. Focus on the analysis of how the material parameters of finite element creep analysis needed to get through the shift factors method. Finally the actual PMC pipe structure is calculated by this method.The error of FEM result and theory result around 2%, the results show that this method has certain rationality and reliability.
