Résumé

In this paper the stress concentration factors are evaluated in 3 zones with cracks on the surface of the cast iron cylinder of the Yankee dryer using a axisymmetric 2D model created in the Ansys Workbench program. The values of the concentration factors are compared with the standardized critical values beyond which the operation does not have safety. The calculation is required in practice during the Yankee cylinder verification stages when non-dangerous cracks can be reconditioned by welding.
