Notes:
A generalization of the (r-1/2) strain or stress singularity capability of the quadratic isoparametric element is presented. It is shown that, by variable placement of the side-nobe between quarter- and mid-point, the point of singularity sensed by the element can be controlled. By using eight-noded quadrilateral isoparametric elements with appropriately placed side-nodes as transition elements between the quarter-point crack-tip trinagular and remaining non-singular elements, stress intensity factors may be computed with higher accuracy.
