“…With the thermal-shock coupling, the maximum stress at the connections will keep rising. Shuye Zhang et al used COMSOL Multiphysics to analyze the mechanical performance of MEMS devices subjected to the coupled load of thermal cycling from −55 °C to 125 °C and 1500 g, 1 ms half-sine pulse shock [ 92 ]. Thermal stress and shock stress tend to cause stress concentration at the same position of the structure, enhancing the damage.…”
