Classification NotesPage 19 of 41S D D2GEW(*) [mm]web thicknessB(*) [mm] web width(*) in the case of 2 stroke semi-built crankshafts:When T H > R H , the web thickness must be considered as equal to:Wred = W – (T H – R H ) [refer to Fig.5]Web width B must be taken in way of crankpin fillet radius centreaccording to Fig.5.The following related dimensions will be applied for the calculation of stressconcentration factors in:Crankpin fillet Journal filletr = R H / Dr = R G / Ds = S/Dw = W/D crankshafts with overlapWred/D crankshafts without overlapb = B/Dd o = D o /Dd G = D BG /Dd H = D BH /Dt H = T H /Dt G = T G /DStress concentration factors are valid for the range of related dimensions for which theinvestigations have been carried out. Ranges are as follows:s 0.50.2 w 0.81.1 b 2.20.03 r 0.130 d G 0.80 d H 0.80 d o 0.2Low range of s can be extended down to large negative values provided that:Indian Register of Shipping
