Mechanical characterisation

Mechanical tests and instrumentation

The static and dynamic mechanical characterisation tests for material and structures allow to measure physics characteristics such as Young's modulus and yield strength. The instrumentation of the experiments is performed with different tools such as :

Strain gauges, (very precise measurement of the deformation but on a very local area).

Digital image correlation, (which allows displacement or deformation fields to be measured over a large area using cameras).

The accelerometers...

Load cell.

Static testing machine

The machines and the results reached below are used for classic tests :
