However, they show great promise for tackling fracture problems that have been difficult to handle using standard finite element techniques. They are especially suitable for handling fracture problems which involve topology changes, such as crack branching, merging, etc.Solutions to problems in anisotropic elasticity are important in the strength analysis of advanced composite materials and structures. An efficient, available computational tool for stress analysis is the boundary element method (BEM). Reports of its applications to anisotropic elasticity remain rather limited.

In BEM analysis, only the boundary of the domain is discretized and unknown quantities are determined only on the boundaries. Compared to domain-type methods (e.g. ?nite element method (FEM) and meshless methods [18]),The Boundary Integral Equation (BIE) method has occupied me to various degrees for the past twenty-two years. The attraction of BIE analysis has been its unique combination of mathematics and practical application. The EIE method is unforgiving in its requirement for mathe matical care and its requirement for diligence in creating effective numerical algorithms. The EIE method has the ability Youn, Seungwon, "Application of displacement and traction boundary integral equations for fracture mechanics analysis " (1993).

If these assumptions are valid, one can perform fracture-mechanics evaluations without having to conduct any full-scale elastic–plastic ?nite element analysis.Using the boundary element method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture surfaces. The computational cost of the BEM is alleviated by using a low-resolution mesh and interpolating the resulting stress intensity factors when propagating the high-resolution crack-front.A two-dimensional isogeometric boundary element method for linear elastic fracture X.
