${\partial }^2(\mathrm{TO})$: A Dual Topological Derivative-Based Enriched Topology Optimization for Fracture Mitigation in 3-D Brittle Solids

Majd Kosta, Shangru Liu, Alejandro M. Aragón

We propose a fracture-mitigation topology optimization framework for 3-D brittle solids. The topology is described by a level set function parameterized by radial basis functions,…
