The Effects of Pressure on the Fracture of Composite Materials

ABSTRACTThe use of tensile tests with superimposed hydrostatic pressures enables a variety of combinations of equivalent stress and mean stress to be obtained. In conventional metallic materials the use of tests under superimposed hydrostatic pressure is of value in the study of processes such as ductile fracture which involve dilatent events such as void nucleation and growth. Quantitative models of ductile fracture and fracture mechanism maps …
