Pesca Pubblicazione scientifica Whipping Investigations Based on Large-Scale Measurements and Experimental Fatigue Testing FILONE TECNOLOGICO TEMA economia circolare e sostenibilità RIASSUNTO AbstractWave loads and slamming loads acting on the ship's hull lead to super-position of low-frequency wave-induced stresses and high-frequency stresses from whipping as well as springing effects. The question to which amount the latter contributes to the total fatigue damage of struc-tural details is still under discussion. Furthermore the question to which amount high-frequency effects are covered by the Rule-based design loads is not finally solved. Also, fatigue damage assessment typically relies on rainflow counting and Palmgren-Miner Rule for linear damage accumulation but it is not yet proven whether this approach works well for superimposed high- and low-frequency stresses. Loads recorded in full-scale measurements onboard of a containership are the basis of this investigation. Fatigue assessment of measured stress shows a signifi-cant damage increase due to high-frequency contribution. However, it has to be emphasized that this is not reflected by observed damages of the fleet in service. To get more insight into the fatigue damaging mechanism of combined low- and high-frequency loads, fatigue tests have been performed in cooperation between DNV GL and TUHH. Transverse stiffeners on a continuous plate have been selected for tests as a representative structural detail. The Palmgren-Miner rule will be verified by test series with measured unfiltered as well as with low-pass filtered loads sequences.
