Failure Criterion of a Typical Polyamide Cured Epoxy Adhesive

Abstract
The use of adhesive joints as structural elements is increasing rapidly. A thorough understanding of failure behavior of bulk adhesive is essential in analyzing the failure mode of adhesive joints.1 This article discusses existing failure criteria for continua under multiaxial stress fields in most general terms. From this general description, an attempt was made to formulate by simple experiments the specific failure criterion of a typical polyamide cured epoxy adhesive, which is to be an input for the failure analysis of a given adhesive joint system utilizing the same adhesive.
