Application and analysis of stiffened side shell panel failure for naval patrol craft

[摘要] (cont.) Using one of the failure incidents that took place on the U.S. Coast Guard 123;;, local failure modes are examined across several analysis methods for axially loaded panels. Buckling and ultimate load values are calculated through a parametric design space, while boundary conditions and geometric properties are varied. Finite element analysis and proven analytical methods are used, including those developed by Von Karman. A comparison analysis is completed using experimental data, where local causes for strength reduction in panels are considered, including construction imperfections, shearing, residual stresses, cracking, and initial deflection.
