BilinearHoffman
Bilinear Hardening Hoffman Model
Syntax
material BilinearHoffman (1) (2...7) (8...10) (11...19) [20] [21]
# (1) int, unique material tag
# (2...7) double, six moduli: E_{xx}, E_{yy}, E_{zz}, E_{xy}, E_{yz}, E_{zx}
# (8...10) double, three poissions ratios: v_{xy}, v_{yz}, v_{zx}
# (11...19) double, nine yield stress
# [20] double, hardening ratio, default: 0.0
# [21] double, density, default: 0.0Iso-error Map
The following example iso-error maps are obtained via the following script.
from plugins import ErrorMap
# note: the dependency `ErrorMap` can be found in the following link
