Introduction Progressive damage in engineering materials and structures may be induced by materials processing, manufacturing and in-service conditions.
The presence of damage may significantly alter the stiffness and the strength of engineering materials and structures.
Thus, damage analysis is an important issue in engineering sciences such as in material sciences, mechanical engineering, civil engineering and etc.
