Fatigue Life Estimation in Frequency-Domain of Composite and Metallic Structures via CUF and Dirlik’s Method
Elisa TORTORELLI, Giuseppe PALAIA, Erasmo CARRERA
Abstract. This work presents a framework for predicting the fatigue life of composite and metallic structures under random excitations. The framework combines the Carrera Unified Formulation (CUF), Dirlik’s frequency-domain approach, and the Tsai–Hill criterion to evaluate fatigue damage from stress power spectral densities. Results for various laminate configurations show good agreement with FEMAP/NX simulations, demonstrating the accuracy and efficiency of the proposed CUF-based fatigue assessment.
