Thesis title: Analysis of Ballistic Resistance of Multilayered Panels

Supervisors: Luming SHEN , Gwenaelle PROUST

Thesis abstract:

The project is aimed to increase the performance of individual armor panel while decreasing its weight.
The dynamic response of multilayered sandwich plates subjected to ballistic impact will be investigated. The multilayered sandwich plates will include more than three layers, one front layer to blunt the projectiles, core layer to further slow down the projectiles, one back layer to support the other layers, and adhesive layers to bond all layers together. The foam materials will be used as the cores due to their excellent performance-to-weight ratio. The numerical simulations will be implemented firstly using aluminium/polymer foams as cores to provide basic data for investigations. The optimized design will be considered in terms of the performance-to-weight ratio. The quasi-static and dynamic properties of foam materials will be studied by various experimental tests, such as compressive tests, SHPB tests and so on. Based on the above data, one material model to describe the mechanical properties of foam materials will be build up. The quasi-static and dynamic properties of multilayered sandwich plates will be studied by various experimental tests, such as compressive tests, SHPB tests, ballistic tests and so on. A constitutive model to predict the dynamic response of composite sandwich plate with foam cores will be set up, which will include elastic regime, plastic deformation, and failure criterion. This model will be expected to describe the dynamic behaviour of light-weight multilayered sandwich plates properly and will instruct the design of amour panels providing maximum protection with minimum weight.
