    Abstract : This thesis work gives an insight on how to estimate the fatigue damage using transient and spectral fatigue analysis for both uniaxial and multiaxial stress states in case of random vibration base excitation. The transient method involves a rainflow count algorithm that counts the number of cycles causing the fatigue damage, while the spectral method is based on probabilistic assumptions from which an expected value of fatigue damage can be estimated.
