Computational methods in fracture mechanics

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.
