โœฆ Synopsis

An element formulation is suggested to obtain variable order singularities simultaneously at the two neighbouring corner nodes of a 4-noded quadrilateral. The element is useful for modeliing a kinked crack with small kink length. The accuracy is good and this is obtained at a substantially reduced computational cost. Case studies are prcscnted to illustrate the usefulness and the accuracy obtainable.

The formula for the truncation error in the energy product for conforming displacement finite elements is well known and a simple modification of this rule is proposed for nonconforming elements. It is also shown that two distinct types of error affect the convergence of the stress solutions, the se
