Six-noded, isoparametric serendipity type quadrilateral regular/singular elements are used for the estimation of stress intensity factors (SIF) in linear elastic fracture mechanics (LEFM) problems involving cracks in two-dimensional structural components. The square root singularity is achieved in t

In this paper, the dual boundary element method is extended to include the non-linear behaviour of cracking in concrete. The fictitious crack model is used to simulate the pure mode I and mixed mode crack propagation in concrete. The fictitious crack in the fracture zone in front of the real crack t
## Abstract This study presents a novel application of the scaled boundary finite element method (SBFEM) to model dynamic crack propagation problems. Accurate dynamic stress intensity factors are extracted directly from the semiβanalytical solutions of SBFEM. They are then used in the dynamic fract
