Unloading stiffness
WebThe material under compression exhibits high nonlinearity. The gasket material also shows quite complicated unloading behavior. The primary deformation of a gasket is usually confined to 1 direction, that is through-thickness. The stiffness contribution from membrane (in-plane) and transverse shear are much smaller, and are neglected.
