Effects of plasticity on the anisotropy of the effective fracture toughness [PDF]
, 2020 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 and a surfing boundary condition are used to study how the crack propagates throughout the material and the evolution of the effective toughness as a function of the layer ...

Quantitative prediction of the fracture toughness of amorphous carbon from atomic-scale simulations [PDF]
Phys. Rev. Materials 5, 023602 (2021), 2020 Fracture is the ultimate source of failure of amorphous carbon (a-C) films, however it is challenging to measure fracture properties of a-C from nano-indentation tests and results of reported experiments are not consistent. Here, we use atomic-scale simulations to make quantitative and mechanistic predictions on fracture of a-C.

Averaging-based approach to toughness homogenisation for radial hydraulic fracture [PDF]
arXiv, 2022 The homogenisation of the fracture toughness is considered in the context of a propagating hydraulic fracture. The radial (penny-shape) model is utilized, in order to incorporate the impact of the viscosity-toughness regime transition over time. A homogenisation strategy based upon temporal-averaging is investigated.
