The derivation of 'standard deviation of stress - life' fatigue curves from BS5400 S-N lines using weibull probability density function (IM-EST-035)

British Standard BS5400 gives fatigue information to be used in the design of welded structures, the information being in the form of stress range - life curves. For many railway applications, especially for bogies, fatigue damage arises from random time series stresses occurring in the frame due to running over...
