Shock Transmission Analyses of a Simplified Frigate Compartment Using LS-DYNA

Abstract

This report gives results as obtained with finite element analyses using the explicit finite element program LS-DYNA for a longitudinal slice of a frigate's compartment loaded with a shock pulse based on the kick-off velocity concept. Effects investigated are nonsymmetry of the bulkhead, Rayleigh damping, plasticity and imperfections. Measurements of a full scale shock trial are shortly discussed. Variations of masses and stiffness arc investigated to find a better correlation between measurements and analysis results.
