Paper Abstract

Active composite materials with fibers and players of SMA are investigated. The behavior of the SMA composites is studied under thermomechanical loading that provides a complete cycle of the phase transformation in SMA active elements. The models of the descriptions of SMA deformation are developed. The refined theories of the beams and plates are proposed for the strain-stress-state investigation of the SMA composites. The method of solution is developed which is based on the Laplas transformation in view of the phase process parameter. The algorithm of the account of damage accumulations, connected with matrix damages, and also their influence on the active composite's behavior is suggested. The influence of the viscoelastic matrix' properties and damage accumulations on the deformation of the active composite, the capability of an implementation of the two-way shape memory effect and the change of the hysteresis loop should be taken into account at a deformation of an active composite in the compete cycle of the phase transformations.
