“…Lim and Choi et al [10] studied the theory of the biaxial load effects on crack extension in anisotropic solids, using the maximum circumferential tensile stress criterion. Shimamoto et al [11] obtained the stress intensity factors according to various biaxial load ratios in the cruciform specimens of elastic and anisotropic material by the photoelastic and caustic methods.…”

A hybrid method for photoelasticity is introduced and applied to the plane problems of isotropic polycarbonate plates with a central crack under uniaxial and equal biaxial tensile loads. Also, the influences of equal biaxial tensile loads on the isochromatic fringes, stress fields and stress intensity factors near the mixed mode crack-tip have been investigated. The results show that, when an equal lateral tensile load is added to the specimen under uniaxial tensile load, the asymmetric isochromatic fringes about the line of crack gradually become symmetric, and the slope of the isochromatic fringe loop near the crack-tip is inclined towards the crack surface according to the increasing of the inclined angle of crack. Furthermore, the shapes of distribution of all stress components are changed from asymmetric to symmetric. In the equal biaxial tensile load condition against the uniaxial tensile load condition, the values of stress intensity factors are changed little, and only the region of compressive stress of 0 / σ σ x is changed when β ＝0 o , but the values of 0 / I K K are increased and those of 0 / II K K become almost zero, namely, we have the mode I condition when β ＝15 o~4 5 o .

“…The procedure is much more simple: after employing homogenisation, one can simply apply Algorithm 1. However, since the homogenised material is orthotropic, the maximum circumferential tensile stress criterion would need to be reformulated, see for example [19,23]. Moreover, using the homogenised model implies losing the effects of locality, as well as the influence of the internal boundaries on the path, unless the latter aspect is incorporated somehow.…”
