Experimental Validation of a Shape Memory Alloy Constitutive Model by Heterogeneous Thermal Loading Using Infrared Thermography and Digital Image Correlation Conference Paper uri icon

abstract

  • This work introduces the use of digital image correlation together with infrared thermography to study non-uniform deformations due localized heating of equiatomic NiTi. While this short paper focuses on demonstrating the mechanical response of the material to localized heating, future work will also demonstrate calibration and validation of a 3-D constitutive model of the material using the concepts presented here. A comparison is made between the behavior of the material due to localized heating and the behavior due to uniform heating and cooling. The relevant parameters used for calibration of the constitutive model are quantified using the results of an ambient heating and cooling experiment.
