Abstract
The main goal of the present research is to check the suitability of the combined Equivalent Material Concept-Averaged Strain Energy Density (ASED) failure criterion, called EMC-ASED, in predicting the load-carrying capacity (LCC) of notched aluminum plates subjected to mixed mode I/II loading. For this purpose, first, a set of experimental results on the LCC of thin V-notched rectangular Al 7075-T6 plates, that fail by large-scale yielding (LSY) regime, are taken from the open literature. Then, Al 7075-T6, which is a ductile material, is equated with an equivalent linear-elastic isotropic material by means of the EMC. Finally, the EMC is linked to the well-known ASED criterion to predict the LCC of the notched Al 7075-T6 plates. It is revealed that the experimental results could successfully be predicted by means of the combined EMC-ASED criterion without requiring complex and time-consuming elastic-plastic failure analyses.
