Abstract

Abstract

In this paper, using ANSYS 5.7/LS-DYNA, the dynamic stress concentration at the hole edge in a plate subjected to transverse explosive loading was studied. A simple and effective approach based on time-distributive function of energy density was developed to calculate the dynamic stress concentration factor. Numerical results are carried out for fixed supported and simple supported square plates (3 m3 m) with a hole (0.3 m0.3 m) in the center.
