StressCheck Tutorial: Computation of Cross Section Centroid
Abstract: Using intrinsic functions SPCTRX, SPCTRY and SPCTRZ to compute the global X, Y, Z locations of a cross section centroid. The locations are computed through the application of a “dummy” traction (with X=SPCTRX/SPAREA, Y=SPCTRY/SPAREA and Z=SPCTRZ/SPAREA) to the surface or surfaces representing the cross section, and then performing a load check to return the X, Y, Z locations of the centroid.

“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®.”
