TL;DR: In this article, the effect of the particle clustering behavior on the mechanical response of metal matrix composites has been analyzed based on the analysis of the von Mises effective stress and the strain in the matrix and in the particles.

TL;DR: In this article, the atomic structures and energies of symmetrical tilt grain boundaries (GB{close_quote}s) in diamond have been calculated over a wide range of misorientation angle using a many-body analytic potential, and for some selected short-period grain boundaries with tight-binding and first-principles density functional methods.
Abstract: Atomic structures and energies of symmetrical {l_angle}001{r_angle} tilt grain boundaries (GB{close_quote}s) in diamond have been calculated over a wide range of misorientation angle using a many-body analytic potential, and for some selected short-period grain boundaries with tight-binding and first-principles density-functional methods. The grain boundary energies from the tight-binding and first-principles methods are about 75{percent} of those calculated with the analytic bond-order potential. The energy rankings of the GB{close_quote}s calculated with the empirical potential, however, are similar to that calculated from the tight-binding and the density functional approaches. Atomic-level energy and stress distributions calculated with the bond-order potential reveal relations between local interface reconstruction and the extent and value of hydrostatic and shear stresses. From the calculated local volume strain and hydrostatic stress fields, the atomic bulk moduli are evaluated, and zones of different elastic behavior in the vicinity of the interface are defined. {copyright} {ital 1999} {ital The American Physical Society}

TL;DR: In this article, the frequency domain formula of equivalent Lemaitre stress taking into account the hydrostatic stress effect is first introduced, and the corresponding method for estimating fatigue life under multiaxial random loading is developed based on multi-axial S-N curve.

TL;DR: In this paper, the development of residual stress and its partial relaxation by diffusion are described and the evolution of microcracks within the residual stress fields are examined, with particular attention devoted to considerations of the critical microstructural dimension at the onset of micro cracking.
Abstract: Brittle materials are subject to microcrack formation at grain boundaries and at second phase particles. These cracks are induced by residual stress that results from incompatibilities in thermal contraction. The development of residual stress and its partial relaxation by diffusion (at elevated temperatures) are described. The evolution of microcracks within the residual stress fields are then examined. Particular attention is devoted to considerations of the critical microstructural dimension at the onset of microcracking.
