Abstract:
1. A method of analyzing structural stress σ s in a localized fatigue-prone region of a structure from a representation of the structure, said method comprising: determining a through-thickness stress distribution σ determining a first component σ where σ x (y) represents said through-thickness stress distribution and t corresponds to the thickness of said structure in said selected cross section; determining a second component σ where y corresponds to a position along said selected cross section, t corresponds to the thickness of said structure in said selected cross section, δ is a value defined in said representation of said structure, σ x (y) represents said through-thickness stress distribution, and τ xy (y) represents a through-thickness shear stress distribution of said structure; and calculating said structural stress σ
