Abstract

This paper deals with the manufacturing of a parallel hydroformed sandwich panel, which is used as a reinforcement for solar panels. The forming process can cause excessive thinning and cracking. Therefore, PAM-STAMP software is used for the analysis of defects. The outputs of the numerical simulation provide information, such as failure pressure, critical areas or limiting deformations. The comparison of the numerical simulation with the experimentally obtained data is created for the validation of these outputs. The comparative criteria are thefailure pressure, the crack zone, and the thickness distribution. Subsequently, the results can be used for a design optimization of the sandwich panel.
