The individual modes of deterioration are described briefly below: Open image in new window Fig. 9 Individual deterioration modes illustrated for a peak-oriented model (Ibarra et al. 2005).
Based on facility conditions and maintenance thresholds, corresponding maintenance actions are selected automatically and the facility switches between deterioration modes to reflect the effects of the chosen action.
"The consumer is, I think, in somewhat slow-deterioration mode which doesn't show up month to month," said David Levy, vice chairman of the Levy Institute Forecasting Center in Mount Kisco, N.Y.
A total of 43 specimens are tested using double-lap shear joints in wet dry and freeze thaw conditions to examine the durability performance of the joint, including load-carrying capacity, interface deterioration, and failure mode.
Low temperature cracking is one of the main deterioration and failure modes for pavements.
Unloading stiffness degradation This mode of deterioration indicates the reduction in both positive and negative unloading stiffness.
Basic strength degradation This mode of deterioration is defined in a way to show a reduction in the yield strength.
Accelerated reloading stiffness degradation This mode of deterioration escalates the target displacement according to the loading trend in both positive and negative directions (Fig. 9d).
This research focuses on investigating the durability of concretes containing fly ash and silica fume exposed to combined mode of deterioration.
Dominating modes of deterioration due to high normal and tangential stresses are wear and rolling contact fatigue.
