Abstract
In this work, a BEM formulation is proposed to analyse cohesive crack using the dual reciprocity method. The solution of the non-linear system of equations is based on the Newton–Raphson process for which the consistent tangent operator is derived. The cohesive crack model is the criterion adopted to describe crack growth particularly for quasi-brittle material problems. The solution is very stable and accurate and can be easily applied to solids that exhibit many crack or micro-cracks. Examples are shown to illustrate the applicability of the formulation. Keywords: boundary elements, crack growth, cohesive crack model.
