TL;DR: In this article, a detailed description of the use of minor structures on fault planes in various brittle rocks as indicators of the sense of relative movement is given, where the main kinds of structures described involve sets of repeated secondary fractures (striated or not) which intersect the slip plane in a direction roughly perpendicular to the slip direction.
TL;DR: In this paper, a method is proposed to compute some characteristics of a possible stress tensor related to striations measured in a given faulted area, if several tectonic phases are responsible for the striations, the method separates and determines the successive stress tensors.
TL;DR: Inhomogeneities of the striation pattern that develop during the rise in tension and also during isometric steady state are completely reversible by this procedure.
TL;DR: In this paper, the effect of various geometrical parameters of a grooved staggered herringbone micromixer on the mixing performance has been investigated using computational fluid dynamics, and the results show that the number of grooves per mixing cycle does not affect the mixing quality in an important way.
TL;DR: In this paper, a large grained long life push-pull fatigue specimens of 99-999% purity copper have been examined at 10% and 50% of the expected life.
Abstract: Large grained long life push-pull fatigue specimens of 99-999% purity copper have been examined at 10% and 50% of the expected life. Carbon replicas of slip striations were examined, interference microscopy was used to measure the displacement across the striations and dislocation structure was examined by transmission electron microscopy. The total length of slip striation in a given area was measured as a function of fatigue life. After polishing the surface the pattern of slip striations which appeared when cycling was resumed was identical to that removed by polishing. The observations indicate that the slip striations are produced by a very large number of related dislocation sources situated in the planes of the striations. Intrusions and extrusions may be built up by the operation of two dislocation sources near the surface on closely adjacent parallel planes, one operated by a tensile stress and the other by the compressive stress. It is suggested that annealing a specimen after half the ...
