Abstract:A model combining the micromechanical reasoning with macroscopic thermodynamic concepts is formulated in this paper for damage evolution in microfractured materials. Fractures correspond to a region of small thickness, along which mechanical and physical properties of the material are degraded. Unlike cracks, fractures are discontinuities able to transfer stress and, therefore, can be regarded from a mechanical viewpoint as interfaces endowed with a specific behavior under normal and shear loading.
