Analytical solution based on HyperGeometric function for spectral fatigue life prediction under Broad-Band random loading

In this study, an analytical method for fast spectral fatigue-life prediction under Broad-Band random loading is proposed. It is based on the power spectral density of stress in the structure and the Rice peak stress distribution of a stationary Gaussian random process. The novel solution is based on special HyperGeometric function which analytically describes the transcendent error weighting function inherent in the Rice model. HyperGeometric-based solution possesses higher accuracy than other currently existing approximate method based on the Rice peak distribution. Straightforward computational applicability of obtained results is accented.
