## Abstract Partition of unity enrichment techniques are developed for bimaterial interface cracks. A discontinuous function and the twoβdimensional nearβtip asymptotic displacement functions are added to the finite element approximation using the framework of partition of unity. This enables the d
In order to define a proper bimaterial stress intensity factor, a general solution for the collinear interface cracks between dissimilar anisotropic media is applied to the near tip of an interface crack. Through the operation of normalization, scaling, nondimensionalization and transformation, a co
A tensile plate with a circular hole is investigated. The notch stresses are calculated, for an optimum notch arrangement as well as cold expansion of the notch. The stress-intensity factor is calculated for a crack originating at a single circular hole surrounded by two axially arranged circular st
