Abstract
Abstract
The stress intensity factor (SIF) of bimaterial is computed by implying XIGA (Extended IsoGeometric Approach) is discussed in research work. The cracks in the plates are varied in their angular orientation to recognize the influence of variation on the slope of cracks. The NURBS-based isogeometric approach simulates the problem of crack & interface under the partition of unity method. The jump at the interface between two materials is represented by the level set function whereas the strong interval at a fracture i.e. crack is represented by asymptotic enrichment & Heaviside function. The method of interaction integral is applied to evaluate the SIF which is validated by results obtained by Pathak [60].
