Sun bench Reloaded

Independent of the structures boundary conditions, shape… stresses tend to be smooth when the structure is subjected to a specific load, considering also there are no stress concentration zones. The sun bench structure works no differently. An interesting point is that the angled leg is weaker compared to the vertical part of the leg.

This work was done in FreeCAD from the geometry design to the FEM setup. Material data used was a simple isotropic ABS from FreeCAD database. The load considered was for a 100Kg load. Supports used were fixation lines at the profile bottom borders.
