Computational Methods for Estimating Rail Life
… the life of a rail is typically estimated using fracture mechanic or fatigue methods and an assumed flaw geometry. Multiple models ranging from complex elastic-plastic finite element models to simplified representations of a beam on an elastic foundation have been developed to predict the life of …

Effect of Galvanic Corrosion on Crack Propagation of Cold Expanded Holes in AA2024-T3
… improve a structure’s fatigue life, processes on mechanically fastened joints have been a topic of focus as it is naturally a discontinuity in the material leading to a local stress concentration under loading. Cold expansion is a well-known technique with a wide range of applications in both new …

The Solution of Hypersingular Integral Equations With Applications in Acoustics and Fracture Mechanics
… technique for solving such equations.</p> <p>Fracture mechanic studies are performed using the aforementioned techniques. We focus our studies on problems addressing the Stress Intensity Factors (SIF) of a finite Griffith crack scattering an out of plane shear wave. In addition, we consider …

Borehole Breakouts in Transversely Isotropic Posidonia Shale
… borehole breakouts or drilling induced tensile fractures, may lead to poor cementing of the borehole annulus, difficulties with recording and interpretation of geophysical logs, low directional control and in the worst case the loss of the well. If these problems are not recognized and expertly …

Seismic precursor identification method integrating acoustic emission physical models and multi-source data
… time. Earthquakes result from macroscopic rock fracture in the Earth's crust, and their preparation process shares profound physical homology with the cross-scale damage evolution in materials, from microcrack initiation and propagation to macroscopic instability. Acoustic emission (AE), as …
