Computational Methods in Fracture MechanicseBook - 2011
Volume is indexed by Thomson Reuters BCI (WoS).The existence of crack-like flaws cannot be precluded in any engineering structure. At the same time, the increasing demand for energy- and material-conservation dictates that structures be designed with smaller and smaller safety factors. Consequently, accurate quantitative estimates of the flaw-tolerance of structures are of direct concern to the prevention of fracture in load-bearing components of all kinds: ranging from space satellites and aircraft to bone prosthesis and home appliances. This special-topic book comprises nine papers that cover various aspects, of current areas of research in Fracture Mechanics, using innovative and new computational approaches based upon the BEM and meshless methods. A number of topics are addressed, such us dynamic and viscoelastic fracture problems, crack surface contact, fatigue and cohesive crack propagation, and the analysis of cracks in composite and anisotropic bodies. Also presented are innovative formulations for fracture problems, such as Symmetric Galerkin formulations and a Local Boundary Integral Equation for the BEM and a variational element-free technique.This is a welcome guide to a fascinating subject. The nine papers invited to join this volume describe numerical methods for analyzing the path and growth of cracks in structures, particularly the boundary element method (BEM), finite element method (FEM), and meshless methods. Researchers at the University of Seville apply the energy domain integral to three-dimensional interface cracks in transversely isotropic bimaterials, and the applied mechanics department at the University of Erlangen-Nuremberg investigates the influence of crack surface roughness on the behavior of cracks. Other topics include a variational technique for element free analysis of fracture mechanics, symmetric-Galerkin boundary element analysis of dynamic stress intensity factors, and the numerical Green's function extended to the local boundary integral equation.
