The damage of metallic alloys induced by tensile deformation can be well described by Gurson-Tvergaard-Needleman (GTN) model. However, damage growth under intense shear loading, which has been found in micro-/macro-indentation tests, cannot be captured by this model. In this paper, an extension to GTN model is proposed to explain the damage induced by spherical indentation deformation. The nucleation...
