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.

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.

Iceberg calving of Thwaites Glacier, West Antarctica: full-Stokes modeling combined with linear elastic fracture mechanics [PDF]
The Cryosphere, 2017 Thwaites Glacier (TG), West Antarctica, has been losing mass and retreating rapidly in the past few decades. Here, we present a study of its calving dynamics combining a two-dimensional flow-band full-Stokes (FS) model of its viscous flow with linear ...

Multiple crack propagation by DBEM in a riveted butt-joint: a simplified bidimensional approach [PDF]
Fracture and Structural Integrity, 2016 A Multi-Site Damage (MSD) crack growth simulation is presented, carried out by means of Dual Boundary Element Method (DBEM), in a two-dimensional analysis of a cracked butt-joint made of aluminium 2024 T3.

Additive Manufacturing Letters, 2022 The near-net-shape manufacturing in additive manufactured and cast of Al-Si alloys results in a heterogeneous solidification and cooling of the parts, leading to significant gradients in microstructural and defect features as well as deformation behavior.

Sharp contrasts in observed and modeled crevasse patterns at Greenland's marine terminating glaciers [PDF]
The Cryosphere, 2020 Crevasses are affected by and affect both the stresses and the surface mass balance of glaciers. These effects are brought on through potentially important controls on meltwater routing, glacier viscosity, and iceberg calving, yet there are few direct ...

KIc Determination of a 7075 T6 Aluminum Alloy by Critical Distances Theory and LEFM [PDF]
Materials Research, 2023 The Critical Distances Theory has been used in engineering field as a less expensive method to predict failures. Thus, this research aims to evaluate its methods in other materials, like the aluminum alloy 7075 T6, and notches. Two different notches were

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 ...
