Abstract : The influence of combined states of stress on the shear response along material principal directions in off-axis, unidirectional, composite coupons is examined for systems whose matrix material obeys thevon Mises yield condition. Such analysis is motivated by trends in experimental data observed for at least two composite systems that indicate deviation from pure shear behavior along material directions for various off-axis configurations
