Numerical simulation for the deformation of composite wall insulation system

This paper presents the thermal stress characteristics of polystyrene plate - thin plaster wall. Based on thermal stress analysis module of ANSYS software, a three-dimensional element solid5 is selected to mesh the wall model, which can simulate the coupling effects of thermal stress and structural stress field. The critical temperature of hot and cold cycles is taken as the critical temperature condition, which is imposed on the calculation model. Windowless Wall and window wall were modeled separately. Temperature field and deformation distribution were proposed after comparing and analyzing the two simulation results.
