Helpful Hints and Tips: Newton-Raphson Integration Technique for Geometric Nonlinear Analysis
The Newton-Raphson integration technique is recommended when there is strong coupling between membrane and bending effects when analyzing thin domains, and should be used if the Direct Integration technique diverges and/or becomes unstable. The Newton-Raphson integration technique is illustrated for a thin diaphragm with elastic-perfectly-plastic materials under uniform pressure.

“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.”
