simplified dislocation kinetics: dropped relativistic correction of velocity, since the infinite attack frequency already sets a limit for the velocity; dropped second; also dropped the correction term for backward jumps, since it was probably not meaningful
2013-03-21 12:52:29 +00:00

2012-11-29 18:50:25 +00:00
f666f8dcf3

2012-10-29 12:49:28 +00:00
3ecaa9e371
modified multiplication term in order to mimic a discrete distribution of dislocation sources; namely, at high resolution, when there is (on average) less than one source per integration point, a random generator decides whether there is a source in the finite volume or not; if there is one, then the multiplication turns independent of the density and depends only on the velocity/volume times a scalar factor; recovers density*velocity/lambda for large finite volumes
2012-10-19 11:40:17 +00:00
324dfda5a2
added comments (doxygen conform) to phenopowerlaw, added warning on specifying h0_sliptwin as it has no effect

2012-10-02 08:12:53 +00:00

2012-08-23 05:48:21 +00:00
b2aacf9ca4
rates in constitutive_results are taken directly from last converged step and not calculated again; added output of rates for annihilation of screws and deposition of edge jogs on collinear system
