heal.abstract	The optical evaluation of the complex stress intensity factors at the tips of an inclined central crack in an infinite sheet subjected to a biaxial load at infinity was studied by using the appropriate number of higher-order terms in the series representation for stresses for the isopachic fringe pattern. Improved values for the stress intensity factors can be computed by this method by taking into account the local influence of the higher-order terms on the isopachic fringes. Furthermore valuable information can be extracted from isopachics which are far from the region perturbed by the elastic singularity near to the crack tip core. Experimental evidence with transverse internal cracks in plexiglas plates indicated the possibilities of the method.	en
