David Mercier 11e138150a Update material config file for cp-Ti (alpha) 2014-03-31 16:49:05 +00:00
Franz Roters 04b2011195 reintroduced dislocation hardening for bcc 2014-03-17 15:42:46 +00:00
Martin Diehl bac0e24d21 added parameter to dislotwin 'dipoleformationfactor'. set it to 0.0 to turn hardening due to dipole formation off (like in the updated tungsten example). standard behavior (e.g. a value of 1) is recovered if no value is given 2014-03-13 23:50:55 +00:00
Duancheng Ma 670c0caabc 2014-03-13 12:12:19 +00:00
Martin Diehl ef8fbf4dda introduced case in dislotwin for bcc (peierls stress as critical stress)
renamed some parameters, now exponents (p,q) for slip are per family, shear band got own ones. exponent for twin (r) now per family

fixed bugs in lattice ("empty" interactions should be 1 not zero)

see both Phase examples to check what is needed
