StressCheck Tutorial: Incorporating Contact Pressure Bleed in Resultant Extractions
Abstract: The term “bleeding” means that the tractions associated with the contact pressures may not be zero out of the contact region on their way to zero traction. This can affect the calculation of stress resultants, and therefore the load transfer feedback. Selection only the element faces inside the contact zone, or the contact zone itself, may not be sufficient to represent the stress resultant associated with the contact pressure.

“Of the three FEA products we use, StressCheck® gives me the most confidence when it comes to performing post-processing quality checks on multi-body contact analysis results. StressCheck® has the capability to extract any data of interest and convergence information for that data at any location in the model domain; the other two FEA products do not. And when it comes to interference fit multi-body contact solutions, I haven’t found any software to outperform StressCheck®.”
