Shakedown is a process we associate with plasticity when components are subject to cyclic load - it is the self-generation of residual stresses which tend to supress subsequent excusrsions into the plastic state. A similar phenomeon is observed when a frictional contact is subject to oscillatory shear forces less than those needed to cause sliding. One question which arises is whether the shakedown theorems devised for plasticity may be applied to contact problems, and here I shall start to answer the question.
