Tension-compression asymmetry incorporating in solution the problem of martensitic non-elasticity and direct martensitic transition in beams from shape memory alloy under bend

Abstract:

In this paper the problems of phase transition end martensite inelasticity in beam with solid rectangular cross-section from shape memory alloy (SMA) under bend is solved. Investigation is founded on non-linear model of SMA straining in phase and structure transitions. Tension-compression asymmetry of the SMA stress-strain curves is incorporated. By semi-inverse method, solution of the problem in coupled formulation is obtained. Diagrams of dimensionless neutral surface coordinate for the various dimensionless bending moments are shown. Response of martensite volume fraction on dimensionless beam curving is obtained.
