A Fully Coupled Micro/Macro Theory for Thermo-Electro-Magneto-Elasto-Plastic Composite Laminates

摘要

This paper presents a micro/macro theory for determining the coupled thermo-electro-magneto-elasto-plastic behavior of arbitrary composite laminates. Two models are considered. The first is the electro-magnetic generalized method of cells micromechanics model (EMGMC) introduced by Aboudi in NASA/CR-2000-209787. Herein, EMGMC has been completely reformulated to improve its computational efficiency and has been extended to admit arbitrary anisotropic local material behavior (in terms of the thermal response, mechanical response, electric response, magnetic response, as well as the coupling behavior) and inelastic local material behavior. The second model is classical lamination theory, which has also been extended for arbitrary anisotropic material behavior and electro-magnetic effects. The end result is a coupled theory that employs EMGMC to provide the homogenized behavior of the composite plies that constitute the thermo-electro-magnetic laminate. Sample results that illustrate many of the unique aspects of the theory are presented.
