Martin Diehl 6140285ddd small changes (use ip.x instead of 1_ip). Probably we should modify postResults to use the 1_, 2_, 3_, standard notation for ip as well 2015-02-07 18:13:51 +00:00
Martin Diehl e4a94aa72b put changes on algorithm from geom_fromEuclideanDistance into addEuclideanDistance 2015-02-07 17:11:46 +00:00
Haiming Zhang f3bab46275 addthe Cazacu–Barlat (CZ) yield criterion (3D and 2D), Banabic–Balan–Comsa (BBC) Yield Criterion. 2015-02-07 16:58:57 +00:00
Haiming Zhang cdb7795956 1. Add default boundary constraint(no constraint) and initial guess to the dictionary
2. With the boundary constraint of exponential term, now non-quadratic yield criteria (isotropic Barlat 1991, anisotropic Barlar 1991, Hosford) take effect.

Haiming Zhang 0350b1829c 1. Replace curve_fit(see minpack.py) with curve_fit_bound(see damask/util.py), now the boundary constraint can be applied.
2. Transfer the output information into dictionary 'fittingCriteria', compact subroutine 'fit'.

Haiming Zhang ce09e992cc 1. Change yieldStress from 'list' to 'numpy.arrary', thanks to Martin's suggestion (3907);
2. Change '3*3' Cauchy stress tensor to '1*6', now the number of input 'xdata' for fitting is 6*Points, which is less than the former 9*Points.

Haiming Zhang fd75772a3f Fix the bug of calculating principal stresses. Now the fitting result is better for the criteria which expressed in principal stresses.
Thanks to Martin.
