Hemodynamic parameters such as spatial and temporal variations of wall shear stress are intimately linked with the development and progression of CAD. However, the real-time detection of pre-atherosclerotic regions with minimally invasive technology remains an unmet clinical challenge. Here, we sought ...
The interfacial shear coupling (ISC) governs the relative in-plane deformations of layered two-dimensional (2D) van der Waals (vdW) materials, which is significant for both the fundamental theory of solid mechanics and the stability design of 2D devices. Here we study the representative ISC of ...
the development of construction details for coupling beams that can be selected according to the design requirements also is needed. Specifically, depending on the shear span-to-depth ratio and shear stress of the coupling beam, diagonal
Where σ represents the total stress matrix of the guiding shoe. e is the volumetric strain, λ is the Lame constant, G is the shear modulus, β is the thermal stress coefficient. Development of a finite element model for the guiding shoe The MG650/1620 shearer and SGZ1000/2 × 700...
the flow–fiber coupling affects the stress field in the solid composite under load in the range of over ± 10%. In addition, the predictions based on a non-Newtonian modeling of the matrix fluid differ significantly from the Newtonian setup and thus the necessity to consider the shear-thinnin...
It turns out that the introduction of rake-shearing action (RSA) by compression-shear coupling mainly improves the thickening rate and the thickening effect in the low-compression stress range. Moreover, by introducing the RSA, the concentration growth ratio also confirms that the compression-shear...
The composition of deep brittle shale was analyzed by component content and microscopic observations, and its mechanical strength was experimentally determined by direct shear and triaxial mechanical tests. The multi-coupling stress field was established, and the stability of shale was evaluated using ...
Shear strain has a subtle but profound effect on the silicon crystal lattice shown in Fig. 1a. In Fig. 1b, we also show an effective 1D lattice obtained by assuming translational symmetry along \(\hat{x}\) and \(\hat{y}\) and performing a Fourier transformation. (This 1D model forms...
For example, it can be possible to machine the shear groove 62 so that the outer tubular wall 34 separates along the shear groove 62 at a torsional shear stress that is within about 10 percent of a calculated amount; and can even be within about 5 percent of a calculated amount. ...
elastomeric material. The tires are designed to be stiff in themselves; they consist preferably of metal. The torque applied to the coupling is transmitted by generating a shear stress in the rubber layers, so that the structural dimensions can be kept small due to the uniform stress of all ...
