Surface dislocation nucleation by wedge indenter contacts

Abstract:

Dislocation nucleation from a surface in contact with a rigid wedge indenter is studied in the framework of plane strain. First, the equivalent driving force on a singularity is derived in compact form. Using the result obtained, the driving force is then expressed in the form of complex integral formulae in terms of the Kolosov-Muskhelishvili potentials for wedge contacts. Then, by the Rice-Thomson model, a dislocation nucleation criterion is proposed for a surface loaded in contact, from wh...
