Dynamic Fracture Analysis of a Ring-Stiffened Cylinder Subjected to a Strong Acoustic Wave

초록

A dynmic fracture of a ring-stiffened cylinder subjected to a strong acoustic wave is analyzed by two steps:macro and micro analysis. In the macro analysis, the fluid-structure interation of a stiffened cylinder subjected to underwater explosion load is investigated, while the dynamic stress intensity factor of a cracked ring stiffener is determined in the micro analysis.
