Strain Monitoring

What this topic covers

Measure local deformation as structures respond to load and temperature.

Core monitoring ideas

Strain gauges and optical sensors can measure small changes in material deformation.

Strain varies with load path, geometry, temperature and local stress concentration.

Long-term trends need temperature context, stable installation and reliable baselines.

Interpretation limits

Sensor placement should follow the structural question rather than a generic grid spacing.

Evidence and data quality

Calibration, mounting and sensor health are part of the measurement system and must be tracked.

Lifecycle use

Combining complementary sensor types can reduce ambiguity when one measurement alone cannot explain a change.
