Fracture Diodes: Directional asymmetry of fracture toughness
N. R. Brodnik, S. Brach, C. M. Long +4
Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the re…
A criterion for critical junctions in elastic-plastic adhesive wear
Stella Brach, Sylvain Collet
We investigate elastic-plastic adhesive wear via a continuum variational phase-field approach. The model seamlessly captures the transition from perfectly brittle, over quasi-britt…
Effects of plasticity on the anisotropy of the effective fracture toughness
Stella Brach
This paper investigates the effects of plasticity on the effective fracture toughness. A layered material is considered as a modelling system. An elastic-plastic phase-field model…
Variational phase-field continuum model uncovers adhesive wear mechanisms in asperity junctions
Sylvain Collet, Jean-François Molinari, Stella Brach
Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical fitting parameters, which range several orders of magni…
Phase-field study of crack nucleation and propagation in elastic - perfectly plastic bodies
Stella Brach, Erwan Tanné, Blaise Bourdin +1
Crack initiation and propagation in elastic - perfectly plastic bodies is studied in a phase-field or variational gradient damage formulation. A rate-independent formulation that n…
