摘要：

The void growth during symmetric Taylor cylinder impact tests on free cutting (leaded) brass has been determined experimentally. The measured porosities have been compared to predictions using a constitutive model based on the Gurson [1] yield function, implemented within the DYNA3D finite element code. The predictions compare favourably with experiment and accurately predict the development of porous zones within these impact specimens.
