Investigating the Effects of Confining Pressure on Cumulative Damage and the Constitutive Behavior of a Particulate Composite Material

Abstract

In this study, the effect of strain rate on the constitutive behavior and damage state of a particulate composite material under a high confining pressure was investigated. Experimental findings reveal that, for a given strain, the stress and the damage intensity are highly dependent on the strain rate. However, the critical damage intensity is insensitive to the strain rate.
