Identification of the plastic behavior of aluminum plates under free air explosions using inverse methods and full-field measurements Vrije Universiteit Brussel
This article describes an inverse method for the identification of the plastic behavior of aluminum plates subjected to sudden blast loads. The method uses full-field optical measurements taken during the first milliseconds of a free air explosion and the finite element method for the numerical prediction of the blast response. The identification is based on a damped least-squares solution according to the Levenberg-Marquardt formulation. Three ...
