Abstract

In this work, we characterize the performance of composite panels subjected to underwater impulsive loadings by finite element analysis (FEA). First, we present a finite element model that simulates the fluid-structure interaction experiment developed in our laboratory for testing the underwater blast resistance of marine composite panels. Then, we present the methodology used to calibrate this model (possessing a high number of degrees of freedom) from available experimental data presented in another talk. Both deflection profile histories and damage maps are used as a metric to identify unknown model parameters. The dynamic model incorporates layered-shell elements, damage initiation by Hashin criterion and damage evolution laws for laminae and interfaces. The calibrated model will help to improve the blast performance of marine structures by design optimization studies of solid and sandwich panels
