Experimental and finite element investigation on wrinkling behaviour in deep drawing process of Al3105/Polypropylene/Steel304 sandwich sheets

摘要

The three-layer aluminum 3105 – polypropylene – 304 steel components are fabricated using the deep drawing process. Then, finite element (FE) simulation of this process was carried out in ABAQUS software and the results of numerical and experimental studies regarding the effects of blank holder force on wrinkling of blank’s flange and punch force were compared to each other. The results indicate a reduction in wrinkling of the deep drawn cups with increase in BHF. In addition, FE simulation could predict the tearing place in the samples well.
