Helpful Hints and Tips: Nonlinear Load Stepping
Abstract: Load stepping is an incremental approach to achieving a target value for an applied load/displacement. In the event that the nonlinear analysis fails prematurely before reading a target value, load stepping should be used.

“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”
