Summary

Active Composites with Shape Memory Alloys (SMA) filaments and layers are considered with the goal to elaborate methods of simulation of the SMA behavior in composite structures, to create the analytical method for solution of simplest non-connected problems and to set algorithms of the numerical procedure for connected problems, to derive the conditions for closed two way shape memory effects in such composites and to elaborate the optimal design of mechanical parameters of the active materials structures. The constitutive equations are formulated, refined theories of the SMA beams, plates and shells and methods of solutions are proposed. The variation of the Stress-strain State in composite structures with the phase transformations is discussed.
