Our recent work investigates the extension of the microplane formulation to the description of transversely isotropic materials such as shale rock, foams, unidirectional composites, and ceramics. Two possible approaches are considered: 1) the spectral decomposition of the stiffness tensor to define the microplane constitutive laws in terms of energetically orthogonal eigenstrains and eigenstresses; and 2) the definition of orientation-dependent microplane elastic moduli.

Purpose: Under general supervision, the postdoctoral research associate will be conducting research specifically in battery manufacturing R&D to lower cost, raise energy density, increase production yield, and address manufacturing bottlenecks. This incumbent will work in close collaboration with other researchers involved with ORNLs applied energy storage program. This position resides in the Department of Energy (DOE) Battery Manufacturing Facility and the Manufacturing Systems Research Group at the Oak Ridge National Laboratory (ORNL).
