The PSD is then used to calculate the ( m_n ), which are statistical descriptors of the process. Specifically, the zero-th moment ( m_0 ) represents the mean square value of the response. A robust spectral method uses these moments to construct a PDF that accurately models the distribution of stress amplitudes in the structure. vibration fatigue by spectral methods pdf better
