StressCheck Tutorial: 2D vs 3D Cold Working Analysis of a Close Edge Distance Hole
Abstract: Modeling of a 3″x5″ titanium strip with a 0.45″ diameter hole at a short edge distance (ED=1.5*D) from the right edge of the strip. The titanium’s elastic-plastic material is described by a Ramberg-Osgood curve with pure isotropic hardening (i.e. (beta=0). The mandrel insertion/removal nonlinear event is simulated by normal springs + spring displacements.
Planar (plane stress) and 3D (Extrude reference) models are solved via Incremental plasticity theory and residual stresses are studied.

“Small errors in modeling can lead to substantial errors in joint performance prediction. To alleviate this problem, the CAI used the handbook functionality of ESRD Inc.’s (St. Louis, Mo.) trademarked StressCheck® P-version finite element software to develop reusable models of typical joints.”
