TL;DR: In this paper, a model was proposed which explains subsurface cleavage facet formation in large grained, planar slip titanium alloys by the buildup of large hydrostatic stresses at the tip of long, blocked shear bands.

TL;DR: In this article, the effects of lateral confinement on the fatigue behavior of plain concrete were investigated experimentally, and the residual strength and stiffness properties of those specimens that did not fail within a prescribed number of cycles were also assessed.
Abstract: The effects of a lateral confinement on the fatigue behaviour of plain concrete were investigated experimentally. Triaxial cyclic tests on cylinders, with the confining pressure and axial load varying in phase opposition at 1 Hz, were performed in different deviatoric planes. The maximum stress deviator was 90% of the deviator at failure in a given deviatoric plane; the minimum deviator ranged between 70% and 95% of the maximum one. The residual strength and stiffness properties of those specimens that did not fail within a prescribed number of cycles were also assessed. In tests with cycles of equal amplitude (normalized to the triaxial static strength), the fatigue life and residual strength seem to be positively affected by an increase in hydrostatic stress only up to a certain level. With the maximum deviator equal, in a given deviatoric plane the fatigue life usually increases with decreasing cycle amplitude. In one of the deviatoric planes, the cycle amplitude and mean stress were found to have oppo...

TL;DR: In this article, the behavior of double-edge notched specimens of metallic foams in compression was studied numerically, in terms of limit load Flim, as a function of notch depth, a/W, and the plastic Poisson ratio νp.

TL;DR: In this paper, closed-form solutions for consolidation of transversely isotropic porous media under hydrostatic stress are presented to model the time variation of pore pressure, volume strain and strains parallel and normal to bedding.
