Abstract: We present an interpolation scheme for use with material models involving history‐dependent state variables. The interpolation scheme is based on the solution of a constrained optimization problem, to identify the smoothest monotone curve which produces… read more here.

Abstract: Data-driven computations propose a completely new paradigm to the computational mechanics research community and to experimentalists. Classically, admissible material states can only be obtained experimentally for homogeneous stress/strain configurations or using a parametric optimization of… read more here.

DOI: 10.1016/j.compositesa.2019.105494
Abstract: Abstract Damage development in composites is a complicated process, unlike metals where the failure is triggered by unstable growth of a single crack; failure in composites is triggered by interaction of multiple local damage events.… read more here.
