For the validation considered equivalent stress(Von-Mises). Point was selected on the surface of the crank 150mm from the end point. For that point, equivalent stress(Von- Mises) was observed using FEA design modeller and hand calculation. Hand calculated value and FEA values were used to validate the model.
Default stress of that the selected point (150mm from end) is 283.8MPa. 5mm sphere was formed around the selected point and studied behavior of sphere influence. Selected 4mm,3mm,2mm,1mm and 0.5mm and refinement was done to find a convergence value if equivalent stress. Equivalent stress values were different with default mesh values for the validation
