StressCheck Tutorial: TLAP-Bearing Default vs Ignore Moments & Offsets (IMO) Case Study
For a case study of an aircraft fitting with loaded lug bores, the maximum 1st principal stress at the lug root and the part deformation for TLAP-Bearing: Default and TLAP-Bearing: IMO (Ignore Moments & Offsets) was studied. The differences can be significant if the locations of the TLAPs are far away from the midplanes and/or centers of the bores, and/or if there are input moments in the fastener loads.

“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®.”
