Mechanical Behavior of Multimaterial Composite Systems. Interlaminar Behavior.

Abstract

Stress analysis of interlaminar adhesive layer (IAL) within a multimaterial doubler model which was evaluated in the previous years work is further investigated. Two dimensional IAL stress distribution were derived by means of the finite element method, with emphasis on the behavior close to the edges. Thermoelastic behavior of symmetrical and nonsymmetrical models was investigated analytically and experimentally. A direct method for measuring IAL stress and strain distribution was developed and compared successfully with the analytical predictions. These studies provide a wider basis for current and future research into the non-linearity and ultimate behavior of the IAL. (Author)
