Cracking and Fracture of Concrete at Meso-level using Zero-thickness Interface Elements, 2003a,2003b, 2006; Bolander and Saito 1998; Bolander et al. 2000), some based on the regular lattice concept (Schlangen and van Mier 1993;Lilliu and van Mier 2003), and some on the classical continuum-type (Stankowski 1990; Wang and Huet 1993).

Damage and Smeared Crack Models,f microcracks, microvoids, and similar defects. These changes in the microstructure lead to a degradation of material stiffness observed on the macroscale. The term “continuum damage mechanics” was first used by Hult in 1972 but the concept of damage had been introduced by Kachanov already in 1958 i

convulsion

Crack models based on the extended finite element method, of 3D cracks for geometries relevant to engineers in industry. Indeed, initial creation of the mesh and modification of this mesh during the propagation of a crack, remain extremely heavy and lack robustness. This fact was the motivation behind the design of the eXtended Finite Element Method (X-FE
