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 paper, the authors evaluated the relationship between fracture toughness and water absorption fatigue according to different polymer matrices such as epoxy and vinyl-ester composites and found that water uptake of the epoxy composites was found to increase with cyclic times.

TL;DR: Post hoc analyses of data from previously tested bovine and antler cortical bone compact specimens demonstrates that, in contrast to crack initiation approach, the crack propagation approach successfully identifies the superior toughness properties of red deer's antlers cortical bone.

TL;DR: Two parameter approaches to elastic-plastic fracture mechanics were introduced to remove some of the conservatism inherent in the one parameter approach based on the J integral [J. R. Rice, J. P. O'Dowd and M. T. Parkes as mentioned in this paper.

TL;DR: In this article, pull-out and elastic bridging were most frequently observed as the toughening mechanisms in samples with fine-grained microstructures having needlelike {beta}-Si{sub 3}N{sub 4} grains with diameters of 1 microm.
Abstract: Different microstructures in Si{sub 3}N{sub 4} ceramics containing Y{sub 2}O{sub 3} and Al{sub 2}O{sub 3} as sintering additives were prepared by two-step sintering. Pull-out and elastic bridging were most frequently observed as the toughening mechanisms in samples with fine-grained microstructures having needlelike {beta}-Si{sub 3}N{sub 4} grains with diameters of 1 {micro}m. The values of fracture toughness were varied from 6.1 to 8.2 MPa {center_dot} m{sup 1/2} with respect to the microstructural characteristics, characterized by the volume fraction of needlelike grains and their diameter.
