ULTRA RS is a French company working on material characterisation and residual stresses measurement with ultrasounds.
Non destructive testing with ultrasounds is widely used in the industry for crack detection. ULTRA RS uses also the ultrasonic method in order to analyse the material state, regarding residual or apply stresses and mechanical caracteristics.
To propose a non destructive solution based on ultrasounds to our custumers. The ultrasonic technique has many advantages compared to others to measure stresses : it is non destructive, fast, cheap and portable to industrial site.
Our activity fields:
Mechanical engineering - Steel industry
Aeronautics - Space
Energy - Nuclear
Car industry
Railway industry
Pipeline - Building trade
What is the knowledge of residual stresses important for?
To evaluate and improve fatigue life
To avoid induced machined part distortion
To evaluate and improve corrosion resistance
To dealy the apparition of cracks
Different sources of residual stresses:
Non homogeneous plastic deformation
Differential cooling rates
Phase transformations
Residual stresses occur in materials during different manufacturing processes:
