Description:

Behavior of basic viscoelastic models.

What can be modified:
  • model itself,
  • type of loading - force, strain rate or strain control,
  • prescribed value (force, strain rate, strain).
Comments:
  • use ▶/|| button to play/pause the simulation (the simulation is paused by default),
  • when changing the model, the simulation is reset,
  • when changing the control, the simulation is paused (press ▶ button to continue),
  • when moving slider not belonging to current control, the simulation is paused and the control is changed.
  • to preserve reasonable graphic representation, the extreme values of strain are artificially constrained. If such extreme strain value is reached, the strain is stopped (regardless used control).
Notice:
  • stress in the spring depends only on current strain (and vice versa),
  • stress in the dashpot depends only on current strain rate (not at all on the strain itself),
  • stress of combined models depends in general on strain, strain rate and history of loading,
  • in general, strain may be nonzero and/or changing even if stress is zero,
  • in general, stress may be nonzero and/or changing even if strain is zero,
