Quadratic isoparametric elements which embody the inverse square root singularity are used in the calculation of stress intensity factors of elastic fracture mechanics. Examples of the plane eight noded isoparametric element show that it has the same singularity as other special crack tip elements,

AbstractÐIt has been proved that stress and strain singularity does not exist in an 8-node isoparametric element by shifting mid-nodes to other positions, with the exception of a special case for one quarter position with r Γ€1/2 singularity. It is also proven that stress and strain singularity does
