The Influence of Mesh Morphology on the Accuracy of FEM Analysis of Bar with a Ringed Notch under Tension

Abstract:

The paper undertakes the issue of the influence of mesh morphology near the notch on FEM anaysis accuracy. During analyses proposals of free meshes and proposals of mapped meshes have been compared. During the calculations it has been specified how, along with the change of finite element size, mesh quality parameters and stress error change. Selected parameters have been set with values of stress concentration factor. The accuracy of Kt calculations specified during FEM analysis has been compared to other methods.
