A Ductile Damage Model with Inclusion Considerations Three-dimensional Prediction of Cavity Growth in Finite Transformations
An orthotropic porous model for plastic material is presented. It takes into account the size, shape, orientation of a void and the presence of an inclusion inside the matrix. A constitutive theory based on plastic spin is discussed in order to follow the direction of the defect. The model is implemented in commercial three-dimensional finite element software.
