High Pressure and Large Shear Deformation System for Materials Research

Abstract

The goal of this project is to initiate experimental rotational diamond anvil cell (RDAC) research at Iowa State University (ISU) and couple it with our theoretical and computational efforts. Experimental RDAC research will be performed with emphasis on mechanical characterization, effects, and phenomena. In particular, we intend to measure complete stress/strain tensor fields within a RDAC, determine the mechanical and physical properties of phases under high pressure and plastic shear, and quantitatively study the effect of stress and plastic strain tensors on various phase transformations (PTs).
