Calculation of tooth root stresses for spur gearsTooth 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.These online calculations are provided free of charge by MESYS AG. The software is tested and no errors are known, but there is no warranty for the correctness of the results and for the availability of the calculations. The usage is at own risk.
