Those of you that do FEA, has there been any comparison to weight saving vs conservative approaches. For example, we conservatively say the caps handle the bending, the web handles the shear, the skin handles the torque. We design for Compression on the caps. (please correct this if it is wrong). But of course this is not entirely accurate, the ribs and skin and carry-through as a system all contribute to portions of those stress. Does the FEA look at all those aspects at once as a system? Has there been any comparison, and conclusions drawn? Conversely does looking at sub-systems as Free-Bodies traditionally give approximately the same result.
