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.
