Inverse square root, l/x/7, singularity characterizes the stress field at the crack tip of homogeneous isotropic elastic media. This 1/x/7 singularity does not, however, hold for cracks present in inhomogeneous solids; such as, a crack terminating at a right angle to bimaterial interface, which is t
## Us&act-It is shown that the singularity of stresses near the tip of crack in an elastii: bi-material can be obtained by using degenerate triangular elements, the shape functions of which are derived from those classical isoparametric elements. A four node triangular element is tested on two dif
This paper describes a numerical procedure to model the crack front evolution of initially arbitrary shaped planar cracks in a three-dimensional solid. The influence of a bimaterial interface on the fracture path of a semi-elliptical surface crack in a three-dimensional structure is examined. The an
