Journal of Materials Science Aims and scope Submit manuscript

Abstract

It has been previously shown that at relatively high test temperatures/slow test rates crack propagation in thermosetting epoxy polymers occurs in a stable ductile manner. The present paper proposes a mechanism for this type of crack growth based upon a meniscus instability model which both qualitatively and quantitatively accounts for the experimental observations.
