Vortices in Superfluids and Superconductors At temperatures below 2.2 K, liquid helium is a superfluid, meaning that it acts essentially like a fluid with zero viscosity governed by the Euler equations. The fluid is irrotational, except for extremely thin vortex filaments, which are formed by quant...
7. Figure 7a shows the horizontal displacement versus the stress ratio (τ/ σ). The shear strength behavior of the sand and the samples with 4% capsules follow a strain-softing response, while with the increase in the capsules content, the samples with 8% and 12% capsules showed the ...
This model assumes that the steel material exhibits linear elastic behavior, meaning that it deforms elastically under applied loads and returns to its original shape once the load is removed. This simplification allows for a straightforward analysis of the impactor and support system. It is a ...
We notice that the term (\(1-{e}^{-b\alpha }\)) is a normalised term to simulate the evolution of plastic hardening variables with hardening parameters. Hence, the parameter\(Q\)in Eq. (5) must have a unit of stress (Pa), to honour the definition of the plastic hardening variable...
A shear wave is a type of wave occurring in bulk mediums when the particles oscillate perpendicular to the direction of wave propagation. A shear type of loading causes the shear wave. In case of an axial strain, you may check our stress calculator. The shear forces cause a change in the...
I just found that applying an axial load of magnitude σ on both sides of a ductile rod will produce a max in plane shear stress of magnitude σ/2. Why is...
This study shows the significant and nonlinear effect of the competition between dilation and fluid flow on the shear strength of constrained shear bands in fluid-saturated rocks. This effect is conditioned by the contribution of the pore pressure to the yield stress and strength. The pore pressure...
In the narrow sense, the term “renormalization” is usually referred to a particular method in quantum field theory. In a broader sense, this is the appearance of the change in the resulting characteristics of a physical object when interacting with other objects. This broader meaning is conside...
