SIMULATION OF RHEONOMIC PROPERTIES OF SHAPE MEMORY ALLOYS
摘要
The reasons of unique thermomechanical properties of shape memory alloys (SMA) are thermoelastic phase and structural transformations that are diffusionless processes; therefore, SMA properties are, normally, interpreted and simulated as scleronomous. However, the recent experimental data indicate that SMA properties are not completely scleronomous. This article proposes a very simple model for description of rheonomic properties of SMA. The time-dependent behavior of SMA in rigid and soft loading, stress relaxation and stepwise loading under the conditions of martensite inelasticity and superelasticity is described. It was found that modeling results comply well with experimental data.
