Abstract

In the present study, creep experiments at different stress and different temperatures were carried out to study the creep behavior of PMMA (MDYB-3). The results show that the creep behavior of PMMA is significantly dependent on temperature in the temperature range of 20-75°C. It was indicated that the duration curves of creep could be divided into three phases. The Chen theory, Norton formula and exponential expression can be used to describe three phases of creep behaviors, respectively. Furthermore, the creep constitutive model based on the experiment results was introduced and implemented into a user subroutine UMAT of software ABAQUS. The finite element analysis (FEA) results prove that the constitutive model introduced in the paper can successfully simulate the creep behavior of structure made of PMMA.
