Initial shear modulus mu
Webb13 mars 2013 · Comparing the initial shear moduli determined from tension and indentation tests, we find that when the indentation depth is large, the Hertzian solution … The shear modulus is concerned with the deformation of a solid when it experiences a force parallel to one of its surfaces while its opposite face experiences an opposing force (such as friction). In the case of an object shaped like a rectangular prism, it will deform into a parallelepiped . Visa mer In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain Visa mer In homogeneous and isotropic solids, there are two kinds of waves, pressure waves and shear waves. The velocity of a shear wave, Visa mer The shear relaxation modulus $${\displaystyle G(t)}$$ is the time-dependent generalization of the shear modulus $${\displaystyle G}$$: Visa mer • Elasticity tensor • Dynamic modulus • Impulse excitation technique • Shear strength Visa mer The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: • Young's modulus E describes the material's strain response to uniaxial stress in the … Visa mer The shear modulus of metals is usually observed to decrease with increasing temperature. At high pressures, the shear modulus also appears to increase with the applied pressure. Correlations between the melting temperature, vacancy formation energy, … Visa mer
