Similar objects that obey
Similar objects that obey a more complex potential than those that obey this law can be modeled via the Duffing equation, while another class of materials that don't obey this law can be modeled using the Left Cauchy-Green tensor. Another material that doesn't obey it is described using invariants of a Finger Tensor and are named for Mooney and Rivlin. A three-dimensional version of this law requires the use of the 4th-order stiffness tensor. It can be expressed as sigma equals E times epsilon, but is more commonly expressed in terms of restoring force. For 10 points, name this law that states F equals k x, used to describe springs.
