Six-noded, isoparametric serendipity type quadrilateral regular/singular elements are used for the estimation of stress intensity factors (SIF) in linear elastic fracture mechanics (LEFM) problems involving cracks in two-dimensional structural components. The square root singularity is achieved in t
In linear elastic fracture mechanics (LEFM), Irwin's crack closure integral (CCI) is one of the sign&ant concepts for the estimation of strain energy release rates (SERR) G, in individual as well as mixed-mode configurations. For effective utilization of this concept in conjunction with the finite e
modified crack closure integral method with square-root stress singularity elements is given for calculation of strain energy release rate for an in-plane extension of a crack. Case studies are presented to illustrate the improvement in accuracy.
