Impact shear. The maximum shear stress created in a solid round bar subject to impact is given as the equation:"Jourawski formula" 2 (U G / V )(1/2) where U = change in kinetic energy; G = shear modulus; V = volume of rod;and...
When open thin-walled section member is subjected to lateral force along the direction of the x-axis, the shear stress is calculated according to the following equation: (6.33)τ=VxSyIyt If the open thin-walled section member is subjected to shear forces in both directions, the result can ...
Fluid mechanicsLinear constitutive equationsNewtonian fluidShear stress growthTransient effectsViscoelastic fluidShear stress growth curves for viscoelastic fluids at low shear rates are analyzed using two linear rheological constitutive equations, an integral constitutive equation and a mixed type constitutive ...
The diffraction is governed by the Bragg equation: (10.23)nλ=2dsinθ where n is an integer corresponding to the order of diffraction λ is the wavelength of the X-ray radiation θ is the angle of incidence of the crystal plane. Any change in applied or residual stress caused, e.g. ...

2b), depends on the system compressibility, stress released during rupture, and on the degree of poroelastic coupling, which is a property of the rock that varies with depth and confinement conditions. For the same fluid and rock system parameters, and geomechanical conditions, ruptures on ...
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...

Additionally, to investigate further into fluid mechanics during piston pump operation, a tracer was modeled using a so-called marker scalar. This is an advectable scalar field following a general transport equation without specific diffusion. To verify the theoretical modeling, 1.15 mL fluorescein-Na...
