Abstract
A macromechanical approach and scientific principles of the construction of two-phase pseudoelastic composites with pseudoelastic hardening are formulated in the present work for the first time in the case where SMA particles are coherently embedded in the elastic matrix. It is shown that a pseudoelastic hysteresis loop may appear in the macroscopic load-unload cycle as a consequence of microstresses caused by direct and inverse martensite transformations in the SMA particles. We also analyze the process of hardening of the new structure and deduce a theoretical formula for estimation of the crack-growth resistance of pseudoelastic materials.
