Overview
This special issue is dedicated to the memory of Professor D.P. Rooke, who was a leading scientist in fracture mechanics. The handbook "Compendium of stress intensity factors" edited by D.P. Rooke and D.J. Cartwright was published in 1976. Both analytical solutions and numerical results of the stress intensity factors for cracked isotropic two-dimensional plate were collected. As the stress intensity factors are dependent of the configuration of the cracked body and loading conditions on the boundary, it is important to develop efficient and accurate numerical methods to deal with the complicated problems in practical engineering.
Although the finite element method is a matured tool to deal with a general problem in engineering, it is, however, not trivial to investigate the crack propagation and fatigue life with high accuracy. The mesh reduction methods, such as the dual boundary integral method, dislocation method, weight function method, displacement discontinuity method, etc., have their unique advantages for dealing with contact and moving boundary problems such as crack propagation. Recently, the meshless approaches including the local boundary integral equation method, the point collocation method with the radial basis function interpolation or the moving least square approximation, the method of fundamental solution, are getting more popular due to their high adaptive and simplicity in numerical implementation. Furthermore, for the fracture problems with anisotropic or functionally graded materials, the meshless methods present their unique advantages over other traditional methods.
This special issue is devoted to mesh reduction methods and their applications in fracture mechanics. Following methods are of specific interest:
