Abstract

An SMA material model for use with finite element analysis is presented. Experimental results conducted to demonstrate and verify the concept closely matched the results obtained from FEA. Both one-dimensional and three-dimensional variations of the material models were used in the FE analysis. The one- dimensional SMA model was used to model the active twisting of a beam while the three-dimensional model was used to investigate stresses developed in a SMA reinforced smart composite plate. Surface-to-surface contact algorithms, nonlinear kinematics and nonlinear material model of SMA were used in FE analysis. A two-step approach was developed in order to analyze behavior of smart composite plates reinforced by SMA wires. Results from the analysis of changing the shape of wing prototype are also presented.
