Dynamic analysis of dislocation generation due to sudden indentation

The dynamic analysis of an edge dislocation generated under the edge of a rigid smooth indentor applied suddenly to an elastic half-plane is presented. The physical requirement that the indentor edge cannot induce a corner yields an equation relating the dislocation, indentor and half-plane parameters. Study of the equation allows several general observations on the dislocation motion. In particular, a given dislocation moving at a given speed can move along either of two paths below a certain indentation level.
