A circular element centered at the crack tip is constructed. According to the first four terms of Williams stress function, the displacement pattern with singularity is given to the circular element, where unknown parameters are considered as generalized nodal displacements. On the interface between

An improvement of the one-parameter extrapolation method of photoelastic determination of complex (mixed-mode) stress intensity factors at straight or curvilinear crack tips in a plane isotropic elastic medium due to Smith et aL[12, I31 can be achieved by measuring the absolute value of such a facto
THE sraxss distribution in a plate into which a crack is generated has been studied by many investigators. The most earlier contri&tuions are due to Inglis[ll, who studied the stresses around an elliptic hole in an iu8nite plate and to Westergaard [2], who treated the crack problem by the complex. v
A new simple method for the photoelastic determination of Mode I stress intensity factors from isochromatics is proposed. This method takes into account the fact that a considerable part of the error committed in the photoelastic determination of Mode i stress intensity factors Kt at crack tips, bas
