The shear modulus, shear strength, and shear stress-strain response from the three test methods were compared. ... corners and 8.7 mm corner radii) were tested to evaluate the effect of cruciform specimen geometry on the shear stress- strain response. ... The notches were 3.8 mm deep with a notch radius of 1 .3 mm and a notch angle of 90Ad. ... Laminate analysis and the plane-stress form of the Tsai-Wu failure theory1a#39; were used to predict the potential failure location for each ply, anbsp;...
