Mechanics of Advanced Materials Laboratory
This lab specializes on in situ full-field deformation measurement at multiple length-scales. Deformation fields can be mapped with intra-grain resolution over an arbitrarily large area through in house scanning equipment. This provides high resolution and high statistical significance (that normally do not coexist) at the same time. The focus of research is on materials with complicated or multi-physics-coupled constitutive behavior (e.g. coupled thermal-mechanical behavior) and deformation-induced transformation phenomena. Studied topics include deformation physics of hexagonal close packed metals that undergo twin transformation and superelasticity in shape memory alloys that is based on an austenite-to-martensite phase transformation. Multiscale measurement is complemented with multiscale modeling activity that includes polycrystalline averaging techniques and various applications of the finite element method.

Research projects in this laboratory investigate solidification behavior of materials. Effects of process variables like the thermal gradient, convection in the melt, and diffusion at the solid-liquid interface are studied to understand the solute redistribution during solidification. This understanding specifically helps identify the underlying phenomena determining the interface stability, which is crucial in the growth of single crystals. The use of single crystals is essential in many industrial fields such as the electronics industry using single crystal semiconductors to increase the conduction efficiency and the aero-space industry employing single crystal superalloys in jet engines to combat the creep at high temperatures.
