BilinearOO
Bilinear Origin Oriented Model
Syntax
For symmetric response between compression and tension,
| Text Only |
|---|
| material BilinearOO (1) (2) (3) (4) [5]
# (1) int, unique material tag
# (2) double, elastic modulus
# (3) double, yield strain
# (4) double, hardening ratio
# [5] double, density, default: 0.0
|
For asymmetric response,
| Text Only |
|---|
| material BilinearOO (1) (2) (3) (4) (5) (6) [7]
# (1) int, unique material tag
# (2) double, elastic modulus
# (3) double, tension yield strain
# (4) double, tension hardening ratio
# (5) double, compression yield strain
# (6) double, compression hardening ratio
# [7] double, density, default: 0.0

History Variable Layout
Since it is derived from the SimpleHysteresis model, they share the same history
variable layout.
