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.
