Standard for Certification - 2.7-3, May 2011Page 441) The cheek plate welds will be fillet welds all around the outer edge of the cheek plate with a throat thicknessof “a” in mm.2) The cheek plate will be so stiff (in plane) that it is reasonable to assume that the complete weld will beactive in transferring load.3) The fillet welds stress components will vary all around the weld. Pure shear on the throat has been assumed.4) In order to take into account possible uneven (bearing) load distribution between cheek plates and mainplate the cheek plate load has been multiplied by a factor of ≈ 2.0 (i.e. 0.6).A.6 Combined stressAll relevant sections of the padeye from centre hole and below shall be checked for combined stresses. It shallbe documented / justified that the most critical section(s) has been considered in the design calculations.The calculated Von Mises equivalent stresses shall not exceed e . The single stress components should (could)be calculated based on the following assumptions:1) Shear and axial stresses: Evenly distributed2) Bending stresses: Beam theory, elastic distributionDET NORSKE VERITAS
