Elastomers typically have a very low value for this quantity.
In the formula for Griffith's criterion, this value is inversely proportional to the energy release rate G. The area under the curve whose slope is this quantity is the toughness. Elastomers typically have a very low value for this quantity. This value can be determined for a material by taking multiplying one plus Poisson's ratio by twice the shear modulus. Below the yield strength, this value is the ratio of stress to strain. For 10 points, name this measure of an object's stiffness, a quantity having units of pressure that is sometimes named for an English physicist.
In the formula for Griffith's criterion, this value is inversely proportional to the energy release rate G. The area under the curve whose slope is this quantity is the toughness.
{Young's modulus} [or {elastic modulus;} or {modulus} of {elasticity}]
