Macroscopic constitutive law for SMA: Application to structure analysis by FEM

Recrystallization of a Ti-45Ni-5Cu cold-worked shape memory alloy characterized by thermoelectric power and electrical properties

“…The first effect may be related to the release of induced cold-work defects or dislocations, which facilitate the austenite→martensite transformation, with a corresponding increase in Ms 18,23 . The second one is related to an increase in the amount of martensite which is transformed to austenite 24 . This effect can be clearly appreciated from Figure 5, where electrical resistivity of each phase (austenite and martensite) is plotted as a function of the HT temperature.…”

A finite element–based numerical tool for Ni47Ti44Nb9 SMA structures design: Application to tightening rings

“…Videnic et al (2007) have studied the constrained recovery in a thick-walled SMA ring. Peultier et al (2008) have developed a device which consists of the tightening of a shape memory ring on an elastic one.…”

A macroscopic constitutive model of temperature-induced phase transition of polycrystalline Ni2MnGa by directional solidification

“…Many macroscopic models of traditional shape memory alloy were proposed [29][30][31][32][33]. Based on the thermodynamical approach, thermo-mechanically-coupled constitutive models were developed to study mechanical behaviors and exploit its potential features, promoted its wide application in engineering.…”
