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...
The shear stress autocorrelation function has been studied recently by\nmolecular dynamics simulation using the 1/q^n potential for very large n. The\nresults are analyzed and interpreted here by comparing them to the shear stress\nresponse function for hard spheres. It is shown that the hard ...
To this end we supplement the equations of motion for the orientational order parameters by an equation for γ, which then becomes time dependent. Shearing the system from an isotropic state, the stress-controlled flow properties turn out to be essentially identical to those at fixed γ. ...

(Medtronic Neurosurgery) shunt was developed with a design consisting of decreasing hole diameters from the distal to proximal end11,62. However, shear stress will be higher in the proximal holes of these shunts. Based on fluid shear stress equation ofτ = µ du/dy, whereµis dynamic...
In this work we propose that the presence and compressibility of the pore fluids, and the coupled rock-fluid response during coseismic rupture, are essential to understand rupture speed. Fluids fill the pore space of crustal rocks, and pore pressures are essential to understand fault stability. Ho...
Taking into account that the material changes its rheology and apparent viscosity according to magnetic field, a magnetically induced state transition is proposed; by the use of a state transition equation, a constitutive model for shear yield stress is defined, consisting of an expression that ...
Shear stress is known to be one of the main culture factors affecting MSC expansion (i.e., proliferation) and differentiation. Shear stress strongly depends on the viscosity of the fluid and, in the case of MSC culture medium, the fluids are considered as laminar Newtonian fluids. Under ...
The dependence of particle permittivity on the shear stress of electrorheological fluids. A ferroelectric TGS particle/silicone oil electrorheological (ER) fluid is introduced to investigate the dielectric dependence of the ER effect. The dielec...

Similarly, in shear the shear stressτis a measure of the internal resistance of a material to an externally appliedshear load. The shear stress is defined in equation(2.4)(seeFig. 2.4): Sign in to download full-size image Figure 2.4.Shear Stress and Strain ...
