Calculation of tooth root stresses for spur gears

Tooth root stresses for external spur gears are calculated using plane-strain or plane-stress 2D FEA with a quad-dominant mesh and quadratic elements. As results the first principal stress and the equivalent stress is shown. For comparison with ISO 6336 calculations the first principal stress should be used.
