Investigating the Constraint Effect in a Particulate Composite Material

Abstract

In this study, the effect of constraint on the critical Mode I stress intensity factor for the onset of crack growth was investigated in a particulate composite material, containing hard particles in a rubbery matrix. Uniaxial specimens with different specimen thicknesses and initial crack lengths were tested under a constant grain rate of 8 cm/cm/min at room temperature. The tested data was analyzed and the results are discussed.
