Design and manufacture of innovative mechanical material testing system

R&D development for mechanical tests

The speciality of the engineering department is the conception and manufacturing (via an in-house machine workshop) of experimental devices allowing to carry out static and dynamic mechanical tests.

We carry out the engineering, mechanical conception, sizing, manufacturing and development of the devices.

For the design of digital models, we use the CAD software SOLIDWORKS.

We also develop specific force and displacement sensors based on the use of strain bridge gauges

The developed machines can also be equipped with interfaces and with regulations and control systems. Ask us for your customised mechanical material testing system at

Here are some examples of experimental devices made upon request.

Dynamic Bulge test

Dynamic test bulge (patent n°FR3048501)

This innovation allows a bulge with a diameter of 80 mm and a deformation speed of 10/s to be produced in a simple way. The test is monitored by highspeed cameras for image correlation.

Dynamic force sensor

Conception and manufacturing of dynamic sensors including mechanical and electronic parts. Each sensor is sized to best suit your needs, allowing to carry out simple dynamic force measurements. The sensor can be mounted on a mobile or fixed impactor (Dynamic response of a sensor). With attached a dynamic response curve of the load cell capabilities. Another advantage of these sensors is that they do not require an amplifier to measure the load signal.

Hydraulic fret

Custom-made (patented) high mechanical properties hydraulic fret (the capacity of the coupling is limited by the torsional strength of the shaft) for tightening and loosening under load.

The benefits :

  • Allows installation on a smooth shaft
  • Can be coupled or decoupled even if the shaft is in motion
  • Allows transmission of a very high torque/li>
