Crack propagation modeling of strengthening reinforced concrete deep beams with CFRP plates
Materials Research Express, 2021 Fracture analysis of reinforced concrete deep beam strengthened with carbon fiber-reinforced polymer (CFRP) plates was carried out. The present research aimed to discover whether crack propagation in a strengthened deep beam follows linear elastic ...

A modelling technique for calculating stress intensity factors for structures reinforced by bonded straps. Part I: Mechanisms and formulation [PDF]
, 2010 This paper describes a 2D FE modelling technique for predicting fatigue crack growth life of integral structures reinforced by bonded straps. This kind of design offers a solution to the intrinsic lack of damage tolerance of integral structures.

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

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 \(

Modelling of Dynamic Behaviour of Orthotropic Metals Including Damage and Failure [PDF]
, 2012 A physically based material model for metals, with elastic plastic and damage/failure orthotropy is proposed in this paper. The model is defined within the frameworks of irreversible thermodynamics and configurational continuum mechanics and integrated ...

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.

Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]
, 2010 This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.
