shear modulus of plastic

How to find experimentally the Shear modulus for a material.

I am trying to find out the Shear modulus for a wire been hold vertically with weights applied providing the torsional force to the wire, now while fixing the wire with the couplings or setting up the experimental set up, it goes under a little amount of deformation for which i don't know the exact torque as it been done manually,..

Elasticity The Physics Hypertextbook

The quantity that describes a material's response to stresses applied normal to opposite faces is called Young's modulus in honor of the British scientist Thomas Young (17731829). Young was the first person to define work as the force displacement product, the first to use the word energy in its modern sense, and the first..

The use of a variable shear modulus in elastic-plastic models for clays

When modelling the elastic behaviour of a clay it is often convenient to use a shear modulus which is proportional to the mean effective stress, in order to improve the accuracy of modelling. This choice can lead, however, to theoretical difficulties, in that the elastic behaviour may be non-conservative. These difficulties may..

10: Young's Modulus | School of Materials Science and Engineering

Dec 11, 2013 . 10: Young's Modulus. However, how do we know how much strain will occur if we apply a certain amount of stress for any given material? To answer this we refer to Young's modulus, also known as the modulus of elasticity - one of the most commonly used materials parameters. When strains are small, the..

That would make the volume: W 0 T 0 L 0 2 / L , which decreases when you stretch the material. For small strain, the Poisson ratio would approach 1. Poisson ratio should be between -1 and 0.5 for a stable, isotropic, linear elastic material. I don't know what the material is you're testing, but.. A A 0 L 0 L seems more..
