Study of the deformation of a sandwich shield subjected to bird impact: A behaviour analysis tool using vector decomposition
Source abstract
Abstract
In this work, a numerical finite element model of a 1.82 kg bird impacting a sandwich shield at 175 m/s is developed. Different shield designs are simulated and it appears that very different sandwich behaviours can occur, depending on the design. A new tool to analyse the deformation of the sandwich during impact is presented and is used to study the behaviour of a shield. As this tool makes it possible to easily compare the behaviour of different shields, it is used in a screening study to identify the more influential sandwich design parameters. If all design parameters are considered to be independent, the core out-of-plane plastic plateaus appear to be the most important. The core in-plane properties, elastic modulus and density and the back skin thickness have much less influence on the sandwich deformation under impact.
