621 Smart Materials: Design, Modeling, and Applications

Nien-Ti Tsou, National Chiao Tung University
Smart materials are extensively used in many modern devices such as sensors, actuators and medical applications. The origin of their significant properties is typically the microstructures and phase transformation. A wide variety of techniques and numerical models can be used to study how the microstructures/phases form and evolve.

Finite element method captures macroscopic behavior of smart materials, providing design guidelines for the applications; phase field modeling simulates the evolution of the microstructure with order parameters, exploring the possibility of microstructure engineering; molecular dynamics modeling simulates the interaction of atoms, and are applied to reveal the mechanism of interesting phenomenon; ab initio and related atomistic calculations resolve the quantum mechanical details and energetics of materials; CALPHAD thermodynamic modeling uncovers the interactions and phase stability in complex multicomponent materials systems. With the advances in more computing powers and the developments of more sophisticated models, such as the non-linearity, multi-physics coupling, and multi-scales, the computation-based material design, discovery, and optimization have been an efficient approach for modern materials researches.

We aim to provide a forum to present and exchange research results featuring contributions on advancing design and modeling techniques, giving in-depth insight of the mechanism of smart materials.
