## Abstract For the general quadrilateral isoparametric elements with 4(__n__−1) nodes (i.e. __n__ nodes along each side), it is shown that the inverse square root singularity of the strain field at the crack tip can be obtained by a general but simple rule. This amounts to collapsing the quadrilat

Two new boundary elements have been proposed for simulation of variable order singularities at the two ends of an element in two dimensions. The "rst can model the variable order strain singularity at both the ends of the element. The second element can do both the strain and traction singularities
