A general method is presented for determining mixed-mode stress intensity factors Kr and Kn from isochromatic fringes near the crack tip. The method accounts for the effects of the far-field, non.singular stress, Β’o,. A non-linear equation is developed which relates the stress field in terms of Kt,
A new type of finite element is introduced which embodies the inverse square root singularity present near a crack in an elastic medium. Using this element near the tip in two typical cracked configurations, stress intensity factors within 5 per cent of accepted values were obtained with meshes havi
The technique of half-fringe photoelasticity (HFP) was used for the determination of the opening mode stress intensity factor for edge cracked strips in uniaxial tensile loading. The results for four different crack lengths are presented and compared with the available analytical and experimental re
