Shear Modulus Equation The shear modulus is determined by measuring the deformation of a solid from applying a force parallel to one surface of a solid, while an opposing force acts on its opposite surface and holds the solid in place. Think of shear as pushing against one side of a block,...
Fitting of the data with an equation derived from the rate theory of plastic deformation, allows the true flow activation volume to be evaluated by extrapolating the data to an infinite shear stress value. The true flow activation volume compares to the volume a tube confining the polymer chains...
What is viscosity? Learn the meaning and formula of viscosity with equations and examples. Understand the methods of measuring the viscosity of a...
The Spalart-Allmaras turbulence model is a one-equation alternative that can be solved in less time than the full Navier-Stokes equations. Turbulence is difficult to describe mathematically, as it deals with randomness, complex flows, high sensitivity to initial and boundary conditions, and much mor...
In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighbouring particles of a continuous material exert on each
InCFD (Computational Fluid Dynamics), that equation is still used as a function to figure out the shear stress at a wall node. In this SimWiki post, we are going to cover the fundamentals ofy^+as well asu^+, why they are used and why these values are very important!
This equation allows us to calculate what may possibly happen to our material under thermal stress if it is not allowed to contract expand properly. We use our calculations and compare it with ultimate strength of material parameters for tensile, compressive, and/or shear strength to find if a...
