摘要: This paper is concerned with an efficient dual boundary element method for 2d crack problems under antiplane shear loading. The equations are the displacement and traction integral equations. When equation applied on outer one of surfaces, general anti-plane loading can be solved a single region formulation. discretised continuous quadratic elements; however, only surfaces needs to discontinuous elements. Highly accurate results obtained, when stress intensity factor evaluated quarter point element method. Numerical examples provided demonstrate accuracy efficiency present
