Structural and Fatigue Strength in Shipbuilding: Ensuring Integrity and Safety in Maritime Engineering

Abstract

When navigating through water, a ship encounters a multitude of complex forces due to the influence of currents, gravity, and buoyancy. This complexity renders the calculation of both structural strength and fatigue strength particularly challenging. Consequently, the ultimate strength method and the total longitudinal strength method are commonly employed for assessing the structural strength of ships. For evaluating the fatigue strength, which involves numerous additional factors, a more systematic approach is required, typically involving fatigue strength verification and lifespan assessment. This paper explores the methodologies used for calculating the strength and fatigue strength of ship structures.
