Research teams need test machines whose initial characteristics do not always meet their requirements. The Electronic Instrumentation group, in collaboration with the doctoral students, the research technicians and the workshop renovates or realizes test means adapted to the studies.
Traditional creep machines apply a stress on the test piece via a lever arm on which masses are based. The loading is not reproductive and the test is affected by the surrounding vibrations. The replacement of the masses by a servo electric cylinder and a control system makes it possible to control the machine in load or in deformation
These machines make it possible to study the creep, relaxation and fatigue fibers, for a load of 0 to 100g .
This fully refurbished hydraulic test machine is used to control load and displacement on Joule-heated specimens and subjected to rapid temperature changes (1000 °C per second).
Primarily intended for cyclic fatigue studies on polymers, this machine makes it possible to apply :
with an adjustable phase shift between torque and load. It was entirely built at the Centre des Matériaux.
A new version of this machine allows testing with higher loads and immersing the sample in the fluid of choice.
The laboratory has a set of equipments for sensor instrumentation acquired or developed over the years by the ATIE division. This equipments make it possible to instrument all types of sensors and to check the calibration of sensors mounted on the test machines.
