Structural Fatigue Monitoring

What this topic covers

Repeated loading, cycle accumulation and changing response.

Core monitoring ideas

Fatigue develops through repeated stress cycles rather than one overload event.

Monitoring can provide load or strain histories that characterize exposure.

Remaining fatigue life requires structure-specific analysis and is not calculated here.

Interpretation limits

Environmental and operational changes can mimic damage-related trends and should be included in interpretation.

Evidence and data quality

Direct inspection remains important when a signal suggests a local defect or geometry change.

Lifecycle use

This site does not calculate safe remaining life, structural capacity or return-to-service criteria.
