Abstract: We present an adaptive numerical treatment for a recently published model for brittle damage with gradient enhancement. We employ adaptive strategies both in time and space, yielding detailed investigations of the convergence behavior: the damage… read more here.

Abstract: AbstractThis paper deals with a constitutive model suitable for the analysis of quasi-brittle damage in structures. The model is based on incremental energy relaxation combined with a viscous-type regularization. A similar approach—which also represents the… read more here.

DOI: 10.1016/j.cma.2021.114036
Abstract: Abstract We propose a gauge theoretic model for quantifying and evolving spatial defects in the form of micro-cracks in deforming solids. A non-trivial affine connection — the gauge connection, is introduced to accommodate local changes… read more here.
