Abstract

A novel theoretical model for a laminate cantilever beam consisting of numerous superelastic shape memory alloy (SMA) layers, based on the ZM model and Timoshenko theory is introduced. The mathematical equations are first developed to predict and describe the internal material structure of laminated beam, according to the solid phase transformation in SMA layers. Then, the theoretical expression of the moment and shear force for a superelastic SMA composite cantilever beam is derived. The proposed model is validated against a 3D finite element analysis model (FEA), giving very good agreement in each case. The moment-curvature response, and distribution of martensite volume fraction and axial stress along the beam length are investigated.
