| ABSTRACT In the present work, laminated composite plates with surface bonded shape memory alloy sheets are modeled and analyzed based on the modified higher-order shear deformation theory. The energy balance equations in conjunction with Brinson’s SMA constitutive model are used to formulate the heat transfer governing equations. The static responses as well as dynamic characteristics of the plates are obtained using Ritz solution technique. The plates are subjected to mechanical loads with two types of boundary conditions, simply-supported and cantilevered. A Mathematica code is developed to analyze different plate problems. The time response of the shape memory alloy laminated composite plate is studied. The obtained results are compared to the available studies solved by different theories. Parametric studies are conducted to demonstrate the effect of thickness ratio, aspect ratio, material properties, thermal expansion coefficient, and thickness of shape memory alloy sheet on the transverse deflections, natural frequencies, and response time. | ||||
