ABSTRACT
Abstract This paper describes the development of finite element software for the simulation of non-planar crack propagation in three dimensional bodies consisting of generally non-homogeneous quasi-brittle materials. The paper concentrates on relevant topological issues, such as: (i) description of the basic solid; (ii) redefinition of the solid with (non-planar) crack growth; (iii) meshing and remeshing algorithms; (iv) definition of special crack tip elements, defined on an internal solid; (v) strategies to cope with crack branching, interaction and closure; (vi) strategies to deal with crack growth across or in the vicinity of bimaterial interfaces.
