The future must begin sharing that all beings be prepared to share in taking on the world class of all those who are poverty-stricken. This means that to remain as spiritual powers of the enigma of souls we will have to become recognized as part of the ancient powers that were to be he...

aMSW shear strength interpretation from triaxial tests is complicated by the need to use strain level based definitions of shear strength due to the lack of a well defined peak strength and a continued increase in mobilized strength at large strains. MSW切变强度解释从三轴测试由需要使用切变强度由于...
On the other hand, the increase in the peak accelerations at each storey level has also been observed for nearly all gap size values considered. Moreover, the peak energy response curves obtained for the case with SSI show the decrease trend, as compared to the corresponding peak values ...
Sp-ECAE is modified based on the ECAE process. By providing a spiral region just before the intersection of ECAE channels, the cylindrical billet twists about its centerline and accumulates pure shear strains. As Fig. 1a illustrates, an Sp-ECAE die typically consists of three main regions, incl...
That develops a large difference in elastic strains of a press/die system. If the press was fixed for a permanent stroke H, the difference in actual strokes between the first pass and the last pass is from a few millimeters for small billets to dozens of millimeters for large billets. ...
bly due to large strains imposed by ECAP. The average size of bigger grains was 1–3 m, while that of smaller grains varied from 500 to 800 nm. Fine grains of 100 nm were also found in the specimen. Besides zones with clearly formed grains, which ...
It is possible to correlate stresses and strains for a general case, where the elastic properties of a material depend on its orientation and each crystalline system can be characterized exclusively based on its symmetries. In a cubic system, as is the case for aluminum, the stiffness tensor ...
“severe plastic deformation” refers to a group of metalworking processes in which metallic materials are subjected to extremely high strains, in order to obtain ultrafine grains (UFG) typically <500 nm in size or even grains in the nanometer range (NG), thereby significantly improving the ...
