WebThe reason for the deformation is the presence of a second force that resists or prevents the object from moving. This force is in the opposite direction to and opposes the movement. If this spring does not have a force at the top to prevent it from moving, when the load is added it will simple fall. WebPlastic deformation is defined as permanent, non-recoverable deformation. Plastic deformation is not linear with applied stress. Recall if a material experiences only elastic …
