Elastodynamic image forces on dislocations
The elastodynamic image forces on edge and screw dislocations in the presence of a planar-free surface are derived. The explicit form of the elastodynamic fields of an injected, quiescent screw dislocation are also derived. The resulting image forces are affected by retardation effects: the dislocations experience no image force for a period of time defined by the arrival and reflection at the ...
متن کاملRenormalized Energy and Forces on Dislocations
In this work we discuss, from a variational viewpoint, the equilibrium problem for a finite number of Volterra dislocations in a plane domain. For a given set of singularities at fixed locations, we characterize elastic equilibrium as the limit of the minimizers of a family of energy functionals, obtained by a finite-core regularization of the elastic-energy functional. We give a sharp asymptot...
متن کاملImage diagnosis: Perilunate and lunate dislocations.
Perilunate Dislocation Anterior-posterior (AP) view (Figure 1) demonstrates the distal and proximal carpal rows overlapping, as well as a complete radial styloid fracture. Lateral view (Figures 2 and 3) demonstrates dorsal dislocation of the capitate, whereas the lunate remains articulated with the radius. More often seen in young men in their teens to twenties, rather than children or the elde...

متن کاملVariation of large elastodynamic earthquakes on complex fault systems
[1] One of the biggest assumptions, and a source of some of the biggest uncertainties in earthquake hazard estimation is the role of fault segmentation in controlling large earthquake ruptures. Here we apply a new model which produces sequences of elastodynamic earthquake events on complex segmented fault systems, and use these simulations to quantify the variation of large events. We find a nu...
