FEM Examples

Singular/nonsingular behaviour transition in a cantilever beam

slight perturbations of the theoretical clamped/free limit angle test_singolarita_clamped-free_v2005r3.mud

Figure 2d, p.6 sinclair_ii pdf, κ=2; actually plane strain, $\nu=0.3$, critical angle from eq. (2.19).

A questionable ball bearing modeling for axle support

spot welding on a thin walled profile in torsion

steel, 80x80mm square section, 2.5 mm thickness. modeled portion: 40mm in the axial direction, with 1 spot weld whose nominal diameter is 4mm.


where (sorry):

  • “graffa” = flap
  • “lamiera” = metal sheet
  • “punto” = spot [weld]
  • “superiore” = upper
  • “inferiore” = lower
