International audience; To estimate stresses near specimen surfaces, X-ray diffraction (XRD) is applied to titanium alloys. Some of these alloys are difficult to study since they are composed of various phases of different proportions, shapes and sca

A Probabilistic Two-Scale Approach to Predict the High Cycle Fatigue Behaviour of Ti-Al6-V4 Parts Machined by High Pressure Water Jet Assisted Turning

Autor: René Billardon, Pierre Mella, Rodrigue Desmorat

Publikováno v: Advanced Materials Research. :791-796

The high cycle fatigue life of machined parts is affected by the so-called surface integrity induced by the machining process. To model the high cycle fatigue behaviour of turned parts a probabilistic two-scale continuum damage model is developed. Wh

International audience; The surface integrity has a significant effect on the fatigue life of structural components (e.g., landing gears). To estimate sub-surface residual stresses, X-ray diffraction (XRD) is applied to a Ti5553 alloy sample in an in
