Abstract
The effects of jog drag upon the theoretical rate of creep in a material containing a three-dimensional dislocation network are examined and shown to be similar to the effects of solute drag. The general form of the theoretical creep equation for jog drag is : where and In these equations σ⊥ can be identified as the contribution of the dislocation network stress to the external stress at creep rate Similarly [sgrave]j is the contribution of jog drag.Keywords
