Overtraining is also known as chronic fatigue, burnout and overstress in athletes. The consequences include&colon; vortex-induced oscillation, lateral buckling and overstress due to self-weight. All of the fuselage fractures were due to overstress. Despite strengthened airframes, it was possible to overstress the airframe during dive-bombing. Minor overstress eventually results in component failure, but without pyrotechnic display or release of smoke. If visible, the location of failure may present clues to the nature of the overstress. The propeller subsequently failed due to overstress, 1 to 2 seconds later. Nevertheless, Eliot did not wish to overstress the likeness, and recognised the differences. The failure mechanisms of IGBTs includes overstress (O) and wearout(wo) separately. Viscoplasticity is usually modeled in three-dimensions using "overstress models" of the Perzyna or Duvaut-Lions types.
