摘要：

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 materials. Moreover finite elements calculations are carried out to check the influence of geometrical parameters (fraction of porosity, distance between voids) on the damage behaviour. The results are in agreement with the Budiansky model. (C) 2015 Elsevier Ltd. All rights reserved.
