摘要
The aim of this work is to analyze the thermo-mechanical stresses evolution produced during the fabrication sequence of the multi-level UTCS structure. Several non-linear material models have been taken into account during the process modeling. We have therefore resorted to the Finite Element Method for the evaluation of such thermo-mechanical stresses that appears in the manufacturing and stacking process. These efforts are made to optimize the product and process design.
