A shrink-fitted peg subjected to a tensile load (Q5939182)

The problem solved is that of a peg shrink-fitted into a pocket in an elastically similar half-plane, and subject to a remote tensile force tending to extract it. A plane analysis is performed, and the conditions for no-slip of the interface are found, together with the depth of penetration of the slip zone when this condition is not met. The standard Muskhelishvili formulation for an elastic half-plane is used to determine the stress state. Two different types of dislocations are employed: glide dislocations to model slip, and climb dislocations dislocations to model separation.
