This article is a summary of six lectures given by the author at webinar, “Advanced Theories for Deformation, Damage and Failure in Materials” organized International Centre Mechanical Sciences, Udine, Italy, May 3–7, 2021. The topics dealt with mechanisms damage failure, continuum synergistic mechanics, failure theories anisotropic homogenized solids, physical modeling composites containing ma...

A continuum damage mechanics (CDM) based constitutive model has been developed to describe elastic, plastic and damage behavior of porous rocks. The pressure sensitive inelastic deformation of porous rocks together with their damage mechanisms are studied for drained and undrained conditions. Fracture mechanics of microcrack andmicro-void nucleation and their coalescence are incorporated into t...
