SimpleHysteresis

The SimpleHysteresis model is a simplified framework for defining arbitrary backbones with linear unloading/reloading behaviour. The residual strain can be customised according to the specific rules.

History Variable Layout

location	value
initial_history(0)	maximum compression strain
initial_history(1)	maximum tension strain
initial_history(2)	last compression unloading strain
initial_history(3)	last compression unloading stress
initial_history(4)	last tension unloading strain
initial_history(5)	last tension unloading stress
initial_history(6)	residual compression strain
initial_history(7)	residual tension strain
