Work in Progress

Until this page is finished please refer to Media:LC_lock.pdf. Note: There are some errors associated with the junction length calculation in the code provided. These have been addressed and will be included in the forthcoming guide on this page.

This tutorial will:

• Introduce the formation of Lomer-Cottrell junctions in FCC crystals
• Determine the dependence of junction length and strength on the initial orientation of the intersecting dislocations
• Illustrate the mobility of nodes at the intersection of glide planes in DDLAB and ParaDis
• Discuss any limitations associated with DDLAB and/or ParaDiS. Physically the junction should be sessile. But in the simulation, the inner nodes of the junction segment are able to move. The end nodes of the junction are confined to the intersection line as they should.
