A 3- Dimensional Finite Element modelling was carried out to design a semi-elliptical crack surface within the block. The objective of this modelling is to create an elemental crack block which would replace the element from any other uncracked geometry and thus create a crack of arbitrary shape within the uncracked regions. A script was written to use the commercial finite element code ANSYS to design cracked geometries. The principle of the scheme is one of replacement of any 20 noded brick element in an uncracked mesh by "crack block" containing crack fronts. This automatically introduces c...
