Welcome to Banuka!

The fatigue strength of mechanical components is influenced by the residual stresses and surface roughness (grooves) generated by successive passes of the cutting tools. In addition, these 2 factors interact with each other, as the distribution of residual stresses varies within a groove. However, the fatigue curves (SN curves) do not take these parameters into account, and assume that the surfaces are relaxed and perfectly polished. Using our MISULAB software, it is now possible to predict not only surface roughness, but also the distribution of residual stresses in the grooves. This key information, inaccessible until now, opens the way to better prediction of the fatigue strength of safety parts in strategic mechanical systems (aviation, nuclear, etc.). To make progress on this scientific and industrial challenge, we are pleased to welcome Sachintha Banuka Maldeniyaarachchi, a student on a master's placement in the #Erasmus Mundus Joint Master meta 4.0 programme at #Centrale Lyon ENISE. We are collaborating with a fatigue expert, Prof. Etienne Pessard from the #ENSAM Angers #LAMPA laboratory. Stay tuned to find out more!
