Structural Damage & Degradation Mechanisms

What this topic covers

Fatigue, corrosion, cracking, settlement, impact and other ways condition can change.

Core monitoring ideas

Different materials and environments develop different degradation mechanisms.

Monitoring methods should match the mechanism and expected spatial scale of change.

Some damage is highly localized, so broad sensor coverage does not guarantee detection.

Interpretation limits

A baseline should include normal operational and environmental variation so ordinary change is not mistaken for damage.

Evidence and data quality

Monitoring evidence should feed inspection, engineering review and maintenance rather than exist as an isolated dashboard.

Lifecycle use

Lifecycle monitoring should be re-baselined after significant repairs, modifications or sensor-system changes.
