Offshore and marine structures increasingly utilise Functionally Graded Materials (FGMs) because of their superior stiffness and enhanced resistance to damage under combined vibration and cyclic loading induced by waves, wind and operational conditions. This study presents a combined analytical and finite element investigation into the dynamic behaviour of a cracked FGM cantilever beam compared with eight conventional offshore structural steels. A fracture-mechanics-based analytical model, incorporating crack-induced flexibility and stiffness degradation under cyclic loading within a…
