TL;DR: In this paper, it has been found that when copper, alpha-brass, and magnesium are strained at elevated temperatures, cavities appear in the intercrystalline boundaries, and these are more prevalent in boundaries transverse to the tensile stress axis.

TL;DR: In this article, the authors reveal the micromechanisms of fatigue damage formation and evolution with respect to particle topology and grain size and orientation in a rolled 7075-T651 Al alloy.

TL;DR: In this article, shotpeeing was found to affect crack behavior by delaying both crack initiation and crack propagation, and cracks were formed preferentially at the specimen edges, and the crack propagation was higher in the depth direction than along the surface, giving initial quarterelliptical crack fronts with the major axis along the thickness direction.

TL;DR: In this paper, the authors developed a model for fatigue growth of matrix cracks in metals reinforced with aligned continuous elastic fibers, which provides estimates of the tip value of the stress intensity factor amplitude, ΔKTIP.

TL;DR: In this paper, field equations of nonlocal elasticity are solved to determine the state of stress in the neighborhood of a line crack in an elastic plate subject to a uniform shear at the surface of the crack tip.
Abstract: Field equations of nonlocal elasticity are solved to determine the state of stress in the neighborhood of a line crack in an elastic plate subject to a uniform shear at the surface of the crack tip. A fracture criterion based on the maximum shear stress gives the critical value of the applied shear for which the crack becomes unstable. Cohesive stress necessary to break the atomic bonds is calculated for brittle materials.
