AbstractShape Memory Alloys SMA s are used in a wide range of engineering and medicalapplications such as biomechanics robotics aerospace and civil engineering due toparticular characteristics of such metals Exceptional behaviors of such materials are notpredictable by the conventional models and the theoretical and experimental investigationon modeling of shape memory alloys are consequently in progress In order to enhance theexisting approaches to the modeling of SMA s in this thesis the constitutive equations forsuch kind of materials are investigated A three dimensional model based on microplane theory is proposed and further developed to simulate the real behaviors of shape memoryalloys under nonproportional multiaxial loading paths Results obtained from the modelshow considerable advantages of the proposed model over the existing ones especially incase of nonproportional loadings A fully coupled thermomechanical model for SMA wiresis then developed in order to take the effects of strain rate into account The model isformulated within a continuum framework in which the heat transfer from an SMA wire tothe surrounding medium is more accurately than the existing models taken intoconsideration The comparison of the results from the present model and those of the othertheoretical and experimental date shows that the present model is able to predict the SMAbehaviors at different conditions more accurately and is more efficient than the existingapproaches especially in case of cyclic loadings
