Strength Characteristics of Boron Aluminum Composite Subjected to Combined Stresses.
Abstract
Quasi-static combined stress experiments were performed on 50 v/o unidirectional Al/B Composites. The Failure Tensor Polynomial Criterion correlated the experimentally determined failure surface within empirical accuracy. This program has also shown that the compressive axial strength is significantly greater than the tensile axial strength. Combined axial and shear stress fatigue testing has been demonstrated and the results suggest that Al/B composites have good resistance to combined axial-shear fatigue. Preliminary exploration indicates that the stress path may have a significant influence on strength. Additional work in this area is desirable.
