AFCN

Nonlinear Version of AFC

Theory

The difference between the AFC model and this AFCN model is the initial loading part. This AFCN model accounts for additional slip-lock effect.

Syntax

material AFCN (1) (2) (3) (4) (5) (6) (7) (8) [9] [10]
# (1) int, unique tag
# (2) double, elastic modulus
# (3) double, tension yield stress
# (4) double, tension hardening modulus
# (5) double, tension unloading modulus
# (6) double, compression yield stress
# (7) double, compression hardening modulus
# (8) double, compression unloading modulus
# [9] double, non-negative degradation paramater, default: 0.0
# [10] double, density, default: 0.0
