Pilot evaluation of a fracture process zone in a modified compact tension specimen by X-ray tomography [PDF]
Fracture and Structural Integrity, 2017 In the case of quasi-brittle material, there is a zone of non-linear behaving material, near the crack tip. A major part of this zone forms a socalled fracture process zone (FPZ), where mechanisms of material toughening take place.

LEFM☆ is agnostic to geometrical nonlinearities arising at atomistic crack tips
Forces in Mechanics, 2022 Various fields such as mechanical engineering, materials science, etc., have seen a widespread use of linear elastic fracture mechanics (LEFM) at the continuum scale. LEFM is also routinely applied to the atomic scale.

A review on prediction of bone fracture using LEFM
Forces in Mechanics, 2023 Bone fractures are significant health concerns, particularly for the elderly population with osteoporosis. Prediction of the risk of fracture and its prevention can help in reducing the socioeconomic burden of osteoporotic fractures.

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 ...

Crack paths and the linear elastic analysis of cracked bodies [PDF]
Fracture and Structural Integrity, 2015 The linear elastic analysis of cracked bodies is a Twentieth Century development, with the first papers appearing in 1907, but it was not until the introduction of the stress intensity factor concept in 1957 that widespread application to practical ...

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

Thermal fracture characteristics of an interface crack subjected to temperature variations
Production Engineering Archives, 2020 Thermal fracture characteristics – the thermal energy release rate and thermal stress intensity factor of a semi-infinite crack at an interface between the two elastic isotropic materials, subjected to the temperature variations, are considered in this ...

Push-over analysis of concrete gravity dams due to flood inflow [PDF]
Numerical Methods in Civil Engineering, 2021 This study numerically predicts the failure scenario of a cracked concrete gravity dam through a push-over nonlinear analysis. The mixed-mode Linear Elastic Fracture Mechanics (LEFM) was employed using the extended finite element method (XFEM).
