StressCheck Tutorial: Modeling a Compression Only Spring Analysis
Abstract: To simulate load transfer to holes, or if a compression-only reaction is desired for a single part, normal springs combined with a Material (or General) Nonlinear analysis may be an efficient workflow:
- Assigning normal spring constraints to select surfaces
- Defining & assigning elastic-plastic material properties to the same surfaces
- Computing a linear & material nonlinear analysis

“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.”
