Identification of residual stresses: problem settings and results.
[ Abstract ]
Identification of residual stresses is an important task in many engineering fields such as fatigue or fracture mechanics, where their presence can significantly increase or decrease the apparent strength of mechanical components.
The present talk will try to make a review of existing problem settings identification results.
More precisely we shall:
1. discuss the linearization procedure strain and materials behaviour in finite elasticity around a stressed state in order to define in a mathematical precise way the problem settings for the identification of residual stresses.
2. present a series of measurement techniques currently used in industry and research for the measurement of residual stresses like the X-ray technique and strain measurements.
3. present existing results in the identification of residual stresses for the different
