Effect of viscosity on cavity growth in ductile damage
Abstract
In this paper the Budiansky approach is used in order to reproduce the void growth measured experimentally by 3D tomography in metals. It permits to avoid the non physical fitting of the alpha coefficient in Huang’s law. This model considers the viscoplasticity of the material to account for the interaction between the voids. It is shown that strain rate sensitivity of the material is playing a key role on growth of cavity and thus on damage of …
