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.

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck® (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
