Nonlinear hinges
The analysis results can be used to generate "force-displacement" and "moment-rotation" graphs for two-node and one-node FEs of nonlinear elastic springs with an account of unloading with initial stiffness (FEs 295, 296). These graphs make it possible to see how nonlinear supports and nonlinear hinges behave based on loading history, which greatly enhances comprehension and evaluation of the structure's behaviour.
