Study of L-extension type ship vibration isolation pedestal based on impedance mismatch principle
ObjectivesAs the traditional pedestal has limited vibration suppression ability, it is necessary to design a new type of pedestal structure to improve its performance in this aspect.MethodsFirst, based on the principle of impedance mismatch, a kind of L ...

Analysis of Fatigue Crack Growth in Ship Structural Details
Fatigue failure avoidance is a goal that can be achieved only if the fatigue design is an integral part of the original design program. The purpose of fatigue design is to ensure that the structure has adequate fatigue life.
