Abstract

A particular weight function method is used in this study to determine the stress intensity factors (SIFs) and T-stresses for offset double edge-cracked plates (ODECPs). By using reference loading conditions prescribed on the crack flanks for finite element analyses, the coefficients of weight functions are derived and compiled in the form of tables. With the weight functions, the SIFs and T-stresses for several loading cases are calculated. The results compare well with those obtained using the displacement method. Applying the derived weight functions, the SIFs and T-stresses for ODECPs under several loading conditions are determined. The results can be used as references for related applications.
