Abstract A two-parameter theory of failure is developed for materials for which the uniaxial compressive stress failure magnitude is less than that for uniaxial tension. The theory is compared with data for a closed cell foam material under combined shear and normal stresses. Although the theory shows the correct general behavior, it probably omits certain finer scale features seen in the data. A more refined theory is now being developed, along with further experimental data.

Abstract Mechanical behavior in tension and fracture toughness of cross-linked PVC foams have been characterized. Young’s modulus, yield strength and fracture toughness data were compared to micro-structural relations derived for open and closed-cell foams. The failure process and stress strain response were indicative of brittle material behavior.
