In conjunction with the quarter-point element, a wide range of stress intensity factor computation techniques may be employed. Of these, the displacement correlation technique (DCT) and the quarterpoint displacement technique (QPDT) have been in common use. It has been suggested by various investiga
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
Abstrae-The rate of introduction of new or quasi-new criteria of fracture is steadily increasing with time. However, the possibilities of combining sound physical principles together with simple notions of realistic concepts in mechanics, in conformity with the existing experimental evidence, are ra
## Abstract The accuracy of the computed stress distribution near the free surface of vertical slopes was evaluated in this study as a function of the element size, including aspect ratio. To accomplish this objective, a parametric study was carried out comparing stresses computed using the finite
