LEFM is agnostic to geometrical nonlinearities arising at atomistic crack tips [PDF]
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.

Fatigue Life Prediction of Notched Details Using SWT Model and LEFM-Based Approach. [PDF]
Materials (Basel), 2023 The fatigue crack initiation life of unwelded steel components accounts for the majority of the total fatigue life, and the accurate prediction of it is of vital importance.

Multi-modal strain mapping of steel crack tips with micrometre spatial resolution. [PDF]
J Synchrotron RadiatMulti‐modal measurements combining X‐ray diffraction, X‐ray fluorescence and optical microscopy allow dynamic crystal recovery effects around martensitic steel crack tips to be studied. The measured strain field around the crack tip shows a significant departure from the predictions of linear elastic fracture mechanics.Due to their superior fatigue ...

International Journal of Fatigue, 2017 The available models for the prediction of fatigue crack growth in adhesive bonds rely on the similitude principle. In most cases, one of three similitude parameters based on the strain energy release rate (SERR) is used; i.e. G max , ( Δ G ) 2 , or Δ G .

Quasi-automatic simulation of crack propagation for 2D LEFM problems
Engineering Fracture Mechanics, 1996 A strategy for quasi-automatic simulation of propagation of arbitrary cracks in two-dimensional, linear elastic finite element models is presented. This strategy has been implemented in FRANC2D (FRacture ANalysis Code 2D). An underlying winged-edge data structure enables automatic local modifications of the mesh along the propagation path without loss ...

LEFM-Nets: Learnable Explicit Feature Map Deep Networks for Segmentation of Histopathological Images of Frozen Sections [PDF]
arXiv.org, 2022 Accurate segmentation of medical images is essential for diagnosis and treatment of diseases. These problems are solved by highly complex models, such as deep networks (DN), requiring a large amount of labeled data for training. Thereby, many DNs possess

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 ...

Italian National Conference on Sensors, 2022 Fatigue of steel bridges is a major concern for bridge engineers. Previous fatigue-based weight-limiting method of steel bridges is founded on the Palmgren–Miner’s rule and S-N curves, which overlook the effect of existing cracks on the fatigue life of ...
