Identification of the Damage Parameters of Aluninium Alloy AA6014 with Inverse Technique

Abstract

Abstract

The AA6014 aluminium alloy used in automobile was studied.The static tensile tests combined with FEM were carried out to get appropriate damage parameters of Gurson.And then the results were validated by dynamic tensile tests.The results show that appropriate parameters which depend on element dimension can be acquired by reverse way.The damage parameter decrease while the sizes increase.In addition,damage parameters are not sensitive to the strain ratio.
