| Title | Multiscale Modeling of Blast Resistant Panels for Military Vehicle Armor (Part 1) |
| Objective | To develop a multiscale structural analysis model of blast resistant panels. |
| Scope | Blast Resistant Panels (BRPs) are metal sandwich structures consisting of two outer sheets sandwiching a honeycomb core, designed to dissipate blast energy through allowable plastic deformation. The deflection and energy absorption of the BRPs under shock loading are to be predicted although, in reality, the deformation of the honeycomb core often requires huge computing resources due to its geometric complexity. In this project, the simulation process is expedited through multiscale modeling. A periodic cell of the honeycomb core is sampled and analyzed in order to obtain its effective characteristics in a homogenized continuum domain. The effective properties of the cell will be replicated in a Finite Element Analysis (FEA) model that consists of a homogenized core instead of a honeycomb core. For simplicity, only rectangular shaped honeycomb cores will be analyzed.This project will be performed by two students. A student who selects this project (part 1) will: (a)study the fundamentals of BRPs, (b)develop a structural analysis model of BRPs, and (c)collaborate with the student in part 2 to understand benefits of multiscale modeling. |
