Edge Pressures Obtained Using FEM and Half-Space: A Study of Truncated Contact Ellipses

open access: yesLubricants, 2022
In rolling or gear contacts, truncation of the contact ellipse can occur, for example, when an undercut extends into the contact area. For an elastic calculation approach, the edge constitutes a mathematical singularity, which is revealed by a ...

Zonal method for contact interaction modeling in the semi-analytical finite element method

open access: yesStrength of Materials and Theory of Structures
This paper presents a comprehensive investigation of contact interaction modeling capabilities within the Semi-Analytical Finite Element Method for prismatic structures. The classical SAFEM formulation assumes material property invariance along the longitudinal coordinate, which leads to the appearance of non-physical tensile stresses in contact ...
