StressCheck Tutorial: Usage of the Force/Moment Method for Arbitrary Cross Sections
Abstract: Usage of the Force/Moment method to apply force/moment vectors to an arbitrarily-shaped cross section through a location in 3D space as defined by a local system. The resulting traction distribution will be a statically equivalent linear stress distribution. When checking the applied Force/Moment load record, using the same local system for the check should return the force/moment vectors.

“We have been having very good success using the P-Version finite element code, StressCheck®, to develop the 2-D solutions for two independent cracks in a plate. I have asked one of our AFGROW team members to model the plate and lug cases using StressCheck® and compare them to the existing AFGROW closed-form solutions. [He] modeled the cases several different ways to be sure that he was getting the best possible solutions. He has verified that the bearing load option in StressCheck® provides excellent results.”
