An adaptive space-time phase field formulation for dynamic fracture of brittle shells based on LR NURBS [PDF]
, 2020 We present an adaptive space-time phase field formulation for dynamic fracture of brittle shells. Their deformation is characterized by the Kirchhoff–Love thin shell theory using a curvilinear surface description.

From finite to linear elastic fracture mechanics by scaling [PDF]
Calculus of Variations and Partial Differential Equations, 2013 The authors describe the asymptotic behaviour of the propagation of a crack in a 2D brittle material. Let \(\Omega \) be a bounded, open and connected domain in \(\mathbb{R}^{2}\) whose Lipschitz boundary \(\partial \Omega \) may be decomposed as the disjoint union \(\partial _{D}(\Omega )\cup \partial _{N}(\Omega )\), with positive Hausdorff measure \(

The effects of residual stress on elastic-plastic fracture propagation and stability
Materials & Design, 2018 Residual stresses in materials affect their resistance to the initiation of fracture and to subsequent crack growth. Using full-field strain measurements and finite element analysis we demonstrate that the effect of residual stress on a material's crack ...
