Evaluation of Stress Intensity Factors for Cracks on the Outside of the Yankee Paper Dryer Using A 2D Axisymmetric FEM Model
Keywords:
stress concentration factor, cracks
Abstract
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.
