However, a relation between fracture behavior and impact load curve has not yet been clarified, and an explanation of the impact load curve has not yet been provided in detail. In addition to this, detailed study about the relation between \\{IMC\\} layer thickness and impact strength has ...
Consider the deformation of fracture voids; the height of the voids not based on the physical measurement of the fracture Hertzian contact theory [76] where u is the normal displacement; and R the radius of the hemispheres (asperity). A series of equal radius spheres simulating the asperity (...
By applying the exponential law to simulate the curve obtained in Fig. 6, we can get the leading factor of I as 4.78 nA. If we consider the micro-explanation from lattice point, then, with the help of the lattice parameter, in a physical sense, the calculated tribo-current should be...
In these conditions, tissue which has a greater ability to undergo elastic deformation and rapid recovery allows the pressure to be distributed more evenly. There are superior cushioning properties in the larger area under the stress–strain curve (and transversal line); this can be ascertained by...
Contrary to ductile materials, the experiments revealed no significant increase in the long-crack threshold, however a pronounced increase in the slope of the R-curve for the threshold of stress intensity range. 展开 关键词: Titanium aluminide R-curve Fatigue threshold Overload ...
Changes in mechanical stiffness of this outer (apical) cell zone are physiologically relevant since they determine the deformation of the cell surface induced by shear stress and thus the release of nitric oxide, one of the major regulators of vascular tone [29]. In contrast to the fine sub...
i have obtained a load-deflection curve in the static analysis with large deflection ON even though it didnt converge. i have applied 100kN and at 69.15kN the solution stopped to converge and the bi-linear isotropic hardening was set ton in engineering data. In the second case, i have ran...
A more detailed explanation is provided here for the form of Equation (6). It is postulated that the kinetics of the crack growth in the zone of intensive plastic deformation and severely embrittled material, which is the so-called transient region, is different from the lattice diffusion-domi...
Static methods require the measurement of tie-rod deformation under a static force to estimate its pre-existent axial load. Several have been proposed, such as those in [3,4,5]. From an operational point of view, the main disadvantages in using a static method are: the need to hang a ...
7 and No. 8 obviously curve during the fracture process. It can also be seen from Table 2 that the curving characteristic parameters of No. 7 and No. 8 are closer to the theoretical parameters under stress control mode. The most reasonable explanation is that the crack growth is controlled...
