Analytical Solutions Using High Order Composite Laminate Theory For Honeycomb Sandwich Plates With Viscoelastic Frequency Dependent Damping, Nan Shan
All Theses
Analytical methods allow parametric changes in geometric and material properties of a honeycomb sandwich plate for studies of stiffness, mass, and damping characteristics with low computational cost. However, studies based on analytical methods are still limited with frequency independent damping models. Specifically, previous analytical models have not consider the frequency dependent damping for viscoelastic honeycomb core sandwich composites, while some work has been done on studying the honeycomb sandwich plate using finite element method, which can be computationally expensive for multiple parameter studies. Therefore, in this work, the honeycomb sandwich plate is studied analytically based on the cellular material theory, …
Design And Analysis Of An Innovative Semi-Flexible Hybrid Personal-Body-Armor System, Daniel Jeffrey Miller
Design And Analysis Of An Innovative Semi-Flexible Hybrid Personal-Body-Armor System, Daniel Jeffrey Miller
USF Tampa Graduate Theses and Dissertations
Current military-grade rifle body armor technology uses hard ballistic plates positioned on top of flexible materials, such as woven Kevlar® to stop projectiles and absorb the energy of the impact. However, absorbing the impact energy and stopping a rifle projectile comes at a cost to the wearer - mobility. In this thesis, a new concept for personal body armor is proposed - a semi-flexible hybrid body armor. This hybrid armor is comprised of two components that work as a system to effectively balance the flexibility offered by a soft fabric based armor with the protection level of hard plated armor. …
