WebThe movement of ice in a glacier is an example of creeping in solids. In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield ... WebFlow Stress. During a metal forming operation, it is important to know the force and power that will be needed to accomplish the necessary deformation.
