On the Convergence of the Mesh-Free Discretization of a Non-Linear Bond-Based Peridynamic Model with a Bond-Breakage Criterion

We show the convergence of a commonly used mesh-free discretization of a dynamic non-linear bond-based peridynamic model with irreversible damage implemented via a bond-breakage criterion for a fixed horizon $\delta>0$. The model chosen here is a mathematically well-posed regularization of a discontinuous peridynamic o...

Aligning feature-mapping designs to given density fields, first and second order

The first Hessian formulation for feature mapping is presented and the behavior of first- and second-order optimizers on benchmark problems is reported, which requires one additional solution of the FEM system per feature variable.
