TL;DR: In this paper, the changes of fault kinematics and the stress field with time in the Baikal Rift System during the Cenozoic were investigated. But the results were limited to the central part of the rift and its southwestern termination.
397 citations
TL;DR: The results suggest that the localization of atherosclerosis in the carotid artery may be due to local variations in both fluid wall shear stress and solid wall stress.
393 citations
TL;DR: In this paper, a review of analytical and numerical models of local stresses around magma chambers, as well as analytical models and numerical examples of dyke-injection and eruption frequencies are presented.
386 citations
TL;DR: In this article, the authors present details of the new WSM database release 2016 and an analysis of global and regional stress pattern, and show two examples of 40 degrees-60 degrees S-Hmax rotations within 70 km.

TL;DR: In this paper, the authors show that the atomic structure of the interface leads to low interface shear strength in non-coherent fcc-bcc nanolayered composites such as Cu-Nb.
Abstract: Recent advances in the fundamental understanding of the deformation mechanisms in metallic multilayers are reviewed. The strength of metallic multilayers increases with decreasing layer thickness and reaches a maximum at layer thickness of a couple of nanometers. The unit processes of slip transmission across the interphase boundary, without the mechanical advantage of a dislocation pile-up, are critical in determining the maximum flow strengths of multilayers. For the case of non-coherent fcc–bcc nanolayered composites such as Cu–Nb, we show that the atomic structure of the interface leads to low interface shear strength. The stress field of a glide dislocation approaching the interface locally shears the interface, resulting in dislocation core spreading and trapping in the interface plane. Glide dislocation trapping at the weak interface via core spreading is thus the key unit process that determines the interface barrier to slip transmission. The maximum strength achieved in a non-coherent multilayer can be tailored by the shear strength of the interface. The role of the atomic structure of the interface in promoting room temperature climb at interfaces and its implications in dislocation recovery is highlighted. Experimental validation of the model predictions is discussed.
