Description:
Behavior of basic elasto-plastic models.What can be modified:
- model itself,
- type of loading - force or strain control,
- prescribed value (force, strain).
Comments:
- when changing the model, the simulation is reset,
- when changing the control, the simulation is paused (press ▶ button to continue),
- to preserve reasonable graphic representation, the extreme values of strain are artificially constrained. If such extreme strain value is reached, the strain does not change (regardless used control).
Notice:
- stress in the spring depends only on current strain (and vice versa),
- strain in the plastic element can change if and only if the stress in the plastic element equals the limit value,
- stress of combined models depends in general on strain and history of loading,
- in general, strain may be nonzero even if stress is zero,
- in general, stress may be nonzero even if strain is zero,
