weac.components.criteria_config module

Module for configuring failure-mode interaction criteria and stress failure envelope selection.

Main fields: - fn, fm: interaction exponents for normal (sigma) and shear (tau) stresses (> 0). - gn, gm: interaction exponents for mode-I (G_I) and mode-II (G_II) energy release rates (> 0). - stress_envelope_method: one of

{“adam_unpublished”, “schottner”, “mede_s-RG1”, “mede_s-RG2”, “mede_s-FCDH”}.

  • scaling_factor, order_of_magnitude: positive scalars applied to the stress envelope.

Typical usage:

from weac.components.criteria_config import CriteriaConfig

config = CriteriaConfig(

stress_envelope_method=”schottner”, scaling_factor=1.0, order_of_magnitude=1.0,

)

See also: - weac.analysis.criteria_evaluator for how these parameters influence failure checks.
