Strain Gauge Measurements Testing (SGT)
Strain gauges can be used to measure static strain due to relatively constant loads such as pressure, thermal expansion.
Strain gauges may also be used to measure dynamic strain due to transient events or vibration.
Strain Gauge TestingInformation from strain gauge measurements is essential for validating finite element analysis (FEA) models, establishing more accurate operating loads, and supporting failure investigations. Why strain measurement matters
Real strain data provides insight into actual structural behaviour under operating conditions, reducing reliance on assumptions and improving engineering confidence.

Applications
|
Strain gauges are ideal for verifying stress and displacement simulation models when measurements are taken at specific locations and correlated with simulation results. Modelling assumptions such as boundary conditions, contacts, and applied loads can be refined to better match observed behaviour. Once the model accurately reflects measured data, more detailed insight into the system becomes available. Updated simulations of the modified system can then be used to predict behaviour with confidence. |

Applications
Strain gauges are ideal for verifying stress and displacement simulation models when measurements are correlated with results at specific locations.
Modelling assumptions such as boundary conditions, contacts, and loads can be refined until the simulation accurately reflects measured behaviour, allowing confident prediction of system performance.
Our combined expertise in strain gauge measurement and simulation ensures seamless investigation and reliable outcomes.
