Micromechanics of porous shape memory alloys Conference Paper uri icon


  • This work focuses on establishing the properties -both static and dynamic - of porous SMA materials, and their energy absorption capabilities. To accomplish this, micromechanics-based analysis of the overall behavior of SMAs is carried out in the present work. The porous SMA is modeled as a composite with a solid SMA matrix, which is in turn described by a constitutive model available in the literature, and elastic inclusions, which in the limit represent the voids in the porous material. The static macroscopic constitutive behavior of the material is established using both the Mori-Tanaka averaging method and the unit cell finite element method. The dynamic macroscopic constitutive behavior is described using the results obtained by the Mori-Tanaka averaging method.
