✦ Synopsis

The main content of this paper is:

(1) To present a proof of singularity with an arbitrary triangular element rather than an isosceles triangular element as R. S. Barsoum did.

(2) To present three numerical examples for the determination of stress intensity factors by using this kind of element for combined mode I and II, mode I and mode 11 cracks.

This communication studies a procedure for stress intensity factor computations using traction singular quarter-point boundary elements. Opening mode stress intensity factors are computed from the tractions' nodal values at the crack tip. A comparison is made between the factors calculated using thi
