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 used StressCheck® on two projects last year, and we were very happy with it. I thank your engineers who provided their insights and suggestions for us during these projects. We really appreciate your team’s contributions this year to the Navy P-8 project. We look forward to working with ESRD again during next year on other Navy projects.”
