Structural Integrity of Intelligent Materials and Structures. Constitutive Modeling of Shape Memory Alloys

Abstract

A full-scale application of shape memory alloys in intelligent structures requires that the complex interaction between active elements (sensors, actuators, processors) and the host material be investigated and a modeling tool to simulate the behavior of these structures be developed. This research is an effort toward this direction with the following objectives: (1) Development of a constitutive theory for pseudoelastic behavior of shape memory alloys based on phase transformation in these alloys; (2) Extension of the theory to finite kinematics and developments of numerical algorithms for solution of the nonlinear pseudoelastic system; (3) Formulation of a multi- director shell theory for finite element modeling of composite laminates; (4) Numerical implementation of the theory in a suitable finite element program with nonlinear capabilities; (5) Simulation of cyclic loading and partial loading/ unloading in shape memory alloys.
