| Popis: | In this paper, the angle between the transformation front and the applied stress of four typical shape memory alloys (SMAs) is investigated analytically and numerically. As demonstrated, the relationship of θ against the applied stress varies according to the transformation strain of a particular SMA. The predicted angle of NiTi in the uniaxial tension is very close to the measured one reported in the literature. It is suggested that θ = 45° may be used as a parameter to classify plane stress problem. |
