Using the complex function method, the dominant values of stress singularities at the tip of a semi-infinite crack which is arbitrarily inclined to and terminated at the bimaterial interface were studied. Numerical values of the dominant singularities were computed for different values of the ratio
The torsional impact response of a penny-shaped crack lying on a bimaterial interface is considered in this study. Laplace and Hankel transforms are used to reduce the problem to the solution of a pair of dual integral equations. The solution to the dual integral equations is expressed in terms of a
The quadratic isoparametric crack-tip elements proposed by R. E. Abdi and G. Valentin (Computers and Structures 33, 241}248) are reconsidered and a simpler method for calculating the optimal position of the side nodes proposed.

The integral approach of Cook and Erdogan was used to obtain the asymptotic behaviour of a crack close to a bimaterial interface. It was found that, in addition to the square-root singularity which dominates the stresses in the vicinity of a conventional crack, there are two additional contributions
