Equation for strain energy
WebThrough Poisson's ratio, we now have an equation that relates strain in the y or z direction to strain in the z direction. We can in turn relate this back to stress through Hooke's law. … WebStress Measures: Usually stress-strain laws are given as equations relating Cauchy stress (`true’ stress) to left Cauchy-Green deformation tensor. For some computations it may be more convenient to use other …
