Abstract:
Ferroic smart materials including shape memory alloys, piezoelectric materials, magnetostrictive materials, etc. have similarities from order parameter to domain structure and macro properties.Modelling these materials based on common physical principles in an integrative fashion might be helpful. However, we still face great challenges in this task, which impact the development and design of new smart materials. It is known that defects play an important role in controlling the microstructural evolution, phase stability and macro properties. In this paper, we focus on the simulation studies of the roles of defects in these smart materials and identify potential opportunities in the search for high performance smart materials.
