โœฆ Synopsis

Ab&aet

-A simple representation for the crack-face disp~cement is emptoyed to compute a weight function soiely from stress intensity factors for a reference loading con~tion. Crack face disputants given by the represe&&n are shown to be in good agreement with analytical resub for cracked tensile strips, and stress intensity factors computed from the weight function agree well with those for edge cracks in half planes, radial cracks from circular holes, and radially cracked rings. The technique involves only simple quadrature and its efficacy is demonstrated by the example computations.

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

A numerical technique for simple and efficient integration of weight functions is presented. The method enables the stress intensity factors to be calculated with the aid of a hand calculator for any non-linear stress distribution normal to the crack surfaces. The proposed integration routine is val

Weight functions for the two surface points of a quarter-elliptical corner crack in a finite thickness plate of infinite width are derived from a general weight function and two reference stress intensity factors. The weight functions have been validated for several linear and non-linear crack face
