摘要
A 3D failure criterion for anisotropic materials that includes stress interactions is developed. The strength tensor model is based on the Gol'denblat-Kopnov criterion, where fourth order strength tensor stress interaction components are computed based on the slope of the failure surface at distinct stress axes intersections. Experimental data from the literature for unidirectional FRP's, an anisotropic paperboard material and textile reinforced composites are used to validate the model. POLYM.
