COMPUTATION OF STRESS INTENSITY FACTORS FOR BI-MATERIAL INTERFACE CRACKS USING THE WEIGHT FUNCTION METHOD
Abstract eng: The stress intensity factor is an important parameter in linear elastic fracture mechanics, in terms of which the fracture criteria can be formulated. In this work, the stress intensity factors for a bi-material interface crack are obtained using the weight function method which has been well established for cracks in homogeneous bodies. The weight functions are determined using the finite element technique based on variational principles to determine the displacement fields for bodies with unbounded strain energy. The selection of approximate singular fields for the weight functions are discussed.
