Numerical Investigations of Thermally Induced Transformation, Reorientation of Martensite Variants and Shape Memory Effect Using Constitutive Model for Accommodation of Transformation Strain

摘要：

To confirm the constitutive model developed by the present authors, example calculations are conducted for the transformation behavior of shape memory alloys. The constitutive model describes the transformation behavior of the material by calculating the transformation stress and strain of transformation systems of micro structures in the material. In the calculating, the accommodation mechanism acting on microstructures of the material is also taken into consideration. Computational results by the constitutive model for these loading paths are revealed to be reasonable in comparing with experimental observations.
