StressCheck Tutorial: Influence of Contact Zone Mismatch on Local Stresses
Abstract: Quantitative measures of the influence of meshing strategies and contact zone mismatches for a simple pin/sleeve bushing assembly. Note: in cases such as this, we observe the “knife edge” effect on the local contact stresses, in which stress “jumps” occur where contact pressure suddenly goes from non-zero to zero. These “jumps” are stress singularities associated with the mathematical model.
- Independent automeshes for pin and bushing, pin contact zone extended outside of pin/bushing overlap region.
- Matching automeshes at pin/bushing termination, pin contact zone extended outside of pin/bushing overlap region.
- Matching automeshes at pin/bushing termination, matching pin/bushing contact zone areas.

“We have been having very good success using the P-Version finite element code, StressCheck®, to develop the 2-D solutions for two independent cracks in a plate. I have asked one of our AFGROW team members to model the plate and lug cases using StressCheck® and compare them to the existing AFGROW closed-form solutions. [He] modeled the cases several different ways to be sure that he was getting the best possible solutions. He has verified that the bearing load option in StressCheck® provides excellent results”
