Share 'Elastic Modulus and Poisson's Ratio'

So, how are stress and strain connected?  For isotropic materials, such as most metals, there are two values that relate values of stress and strain and fully describe a material's behavior when forces are applied.  These are the elastic modulus and Poisson's ratio. The elastic modulus is a measure of the stiffness of a material.  For a given value of stress pulling on an object, increasing the…
