Abstract
This paper presents a thermal-mechanical coupled constitutive model to calculate the stress and temperature distribution of 3D braided composite under impact compressions in high temperature environment. The temperature effect and strain rate effect are involved in the coupled model. A temperature-rise equation in adiabatic state is derived to calculate the temperature rise during the impact compression. A user-defined subroutine was written for numerically simulating the impact damage with finite element method (FEM). The sensitivity of mesh size on the results was analyzed. The results reveal the temperature rise and the coupling stress of the 3D braided composite under different impact compression conditions, i.e., temperatures and compressive loadings.
