Metals, 2022 The airworthiness certification of military aircraft requires a durability analysis be performed using linear elastic fracture mechanics (LEFM). Furthermore, such analyses need to use a valid small crack growth equation.

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 ...

Analysis and Comparison of Some LEFM Parameters
Procedia Structural Integrity, 2019 Abstract This paper presents and analyses a possible extension of the well-known mean Strain Energy Density approach, proposed and developed by Paolo Lazzarin for the strength characterization and for the structural analysis of sharp notches. The new parameter, that here will be defined and discussed only for the case of a crack subjected to mode I ...

Models of buoyancy-driven dykes using continuum plasticity or fracture mechanics: a comparison [PDF]
Geoscientific Model DevelopmentMagmatic dykes play an important role in the thermomechanics of tectonic rifting of the lithosphere. Our understanding of this role is limited by the lack of models that consistently capture the interaction between magmatism, including dyking, and ...

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).

Journal of Glaciology, 2018 We investigate the appropriateness of calving or crevasse models from the literature using linear elastic fracture mechanics (LEFM). To this end, we compare LEFM model-predicted stress intensity factors (SIFs) against numerically computed SIFs using the ...

The influence of firn layer material properties on surface crevasse propagation in glaciers and ice shelves [PDF]
The CryosphereLinear elastic fracture mechanics (LEFM) models have been used to estimate crevasse depths in glaciers and to represent iceberg calving in ice sheet models.

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

BEM/OQM Formulation to Simulate Crack Problems
Trends in Computational and Applied Mathematics, 2008 Over the last few years the Boundary Element Method (BEM) has been successfully applied to linear elastic fracture mechanics problems (LEFM), involving static and dynamic cases. An approach to solve LEFM problems is presented in this work.

Shock and Vibration, 2014 During fatigue damage accumulation, cracks propagate through the material leading to catastrophic failure. As the cracks propagate, the natural frequency lowers, leading to a changing stress state.
