heal.abstract	The optical method of reflected caustics was applied up-to-now to problems of cracked plates under uniaxial loading. Only the problem of the biaxial tension of the plate has been considered for the particular case where the crack is transverse to the longitudinal axis of the plate which coincided with the loading axis. In this paper the influence of a biaxial loading of the plate on the form and orientation of the caustic was studied in connection with the orientation of the crack. New modified relations were given for the evaluation of the complex stress intensity factor K=KI-iKII in terms of the angle φ{symbol} of the angular displacement of the caustic axis. For the accurate evaluation of KI and KII nomograms of correction factors δy′max, δx′max and δx′max were given in terms of the angle of inclination of the crack ω=(90-β) and the biaxiality factor k. Experimental evidence with PMMA internally cracked plates corroborated the results of theory. © 1982 Springer-Verlag.	en
