Nonlinear Response and Integrity of Composite Sandwich Structures
Abstract
The overall objective of the proposed work is to carry out comprehensive research to better understand the response and integrity of composite and sandwich structures under dynamic pressure loads initiated by implosion. In particular, research will be conducted to investigate the effect of structural details including core construction on the dynamic implosion process. Specifically, the research will be conducted via the use of a fluid-structure interaction methodology, coupling a finite element CSD model and a finite element CFD model based on wave propagation, for analysis of composite and sandwich structures under implosion loads, The proposed work includes validation of the developed methodologies via correlation with available experimental data, parametric studies on the response and integrity of cylindrical composite and sandwich structures under implosion loads, and exploring feasibility of controlling implosion process through structural tailoring to mitigate the effect of implosion on the integrity of the host and adjacent structures.
