Crack Driving Force Calculation for a Railway Wheel Considering Thermoplastic Properties of the Wheel Material [PDF]
International Journal of Railway Research, 2020 In this paper, the driving force calculation of a cracked railway wheel is studied, and the effects of thermal loads due to braking, train speed, and elastic-plastic material model are considered.

Size Effect in Fracture: Roughening of Crack Surfaces and Asymptotic Analysis
, 2002 Recently the scaling laws describing the roughness development of fracture surfaces was proposed to be related to the macroscopic elastic energy released during crack propagation [Mor00].

The 1/r singularity in weakly nonlinear fracture mechanics
, 2009 Material failure by crack propagation essentially involves a concentration of large displacement-gradients near a crack's tip, even at scales where no irreversible deformation and energy dissipation occurs. This physical situation provides the motivation

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 \(

An Incremental Cohesive Law for Delamination Under a Mixed Mode Loading
Frontiers in Materials, 2020 Cohesive zone models rely on the formulation of a cohesive constitutive law. The latter describes the relation between displacement and traction in a cohesive element at an integration point.

Crack Growth in Ni-Cr-Mo-V Steel Using ΔCTOD Elastic–Plastic Model
Journal of Marine Science and Engineering, 2022 Many studies have shown that the linear elastic fracture mechanics (LEFM) method based on the stress intensity factor range (ΔK) has limitations that cannot be ignored. Due to neglecting the influence of plastic deformation near the crack tip, LEFM shows
