The processes of material manufacture, processing, machining, and forming may introduce flaws in a finished mechanical component. Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause failure of the flawed structure. Des…

WebbIf an initial crack is wanted, it is very easy to define with XFEM. A separate part representing the crack (without properties or mesh) can be instanced into the assembly and moved to the correct position. By choosing this part as crack location, the crack is defined. The crack does not need to be along the element edges.
