Additional-advanced section properties and stresses are calculated by using FE method based on serendipity 2nd order element discretization.
In detail, Additional-advanced section properties calculation assumptions and theoretical implementation background is described in the literature:
- Walter D. Pilkey. Analysis and design of elastic beams. Computational methods. John Willey. 2002
- B.D. Mixon. The development of a finite element too for the calculation of beam cross section properties. The university of Texas. 2008
Detailed assumptions of stress analysis are described in:
