Ballistic Limit Velocity For Continuous Fiber Polymeric Composite Materials and Polymers Through Experimental and Numerical Methods
Grupp, Jonathan (2015-05-06)
Composite materials are often subject to harsh operating environments which may include impact from errant projectiles of various geometries traveling at specific velocities and trajectories. Experimentalists seek to ...
Construction Technique and Strength of Connected Regolith Bag Structures
Singh, Mandeep (2007-05-15)
Masonry Arches have been used from a long time in construction of bridges, domes and other structures. They are constructed out of voussoirs and their stability is determined by drawing a funicular polygon representing ...
Design and Analysis of Woven Shape Memory Alloy Fabric
Skalitzky, Amanda (2018-11-27)
Shape Memory Alloys (SMA) are smart materials that can memorize a shape and return to that shape after deformation upon the application of stress or heat. The most commonly used SMA is Nitinol (NiTi) which consists of ...
Design, Simulation, and Precision Manufacturing of Flexible-Backing, Morphing Composite Metamaterials that Lock Suddenly in Global Bending
Petersen, Caleb (2021-04-30) ETD File Embargoed
Few composite structures, let alone single materials, are known that undergo sudden but reversible stiffening at a pre-engineered strain profile, especially in global bending. This research builds upon this author’s previous ...
A Machine Vision and Sensing System for Braid Defect Detection, Diagnosis and Prevention During Manufacture
Branscomb, David (2007-12-15)
The mechanical properties of braids are often quite convenient for achieving the high performance levels expected of composite materials. A favorable attribute of a braided structure is the ability for the design engineer ...
Microwave Promoted Addition of Organosiloxanes to Hydroxyl Containing Substrates for Facile Synthesis of Chemical and Biological Warfare Agent Reactive Polymers
Owens, Jeffery (2007-05-15)
The primary focus of this work was the synthesis and characterization of materials efficacious in detoxifying/killing chemical and/or biological threat agent surrogates, including Bacillus anthracis spores, in militarily ...
Modeling and Numerical Simulation of Shape Memory Alloys in Robotics Applications
Lambert, Tyler Ross (2017-07-27)
Shape memory alloys (SMA) are uniquely alloyed metals that have the ability to change crystalline structure upon the application or removal of stress or upon heating or cooling. This change in crystalline structure gives ...
The Synthesis and Practical Applications of Novel N-Halamine Biocides
Barnes, Paul (2006-12-15)
A novel set of N-halamine siloxane precursors were synthesized for the purpose of coating various substrates to determine the factors, which are the most dominant influences of the overall stability of the newly modified ...
Synthesis, Structure-Bioactivity Relationship, and Application of Antimicrobial Materials
Kocer, Hasan Basri (2009-12-14)
Antimicrobial N-halamine compounds were designed, synthesized and applied onto various materials to investigate and develop several properties of the N-halamine-based technologies. There are five projects covered in the ...
Terminal Ballistics of Composite Panels and Verification of Finite Element Analysis
Grupp, Jonathan (2011-07-29)
Composite materials are becoming more prevalent in a wider range of applications due to the inherent advantages afforded by their strength to weight ratio over more traditional engineering materials such as metals. As such, ...
Variable-Stiffness Protective Material
Petersen, Caleb (2016-05-04)
The focus of this research is to develop a system for limiting the motion of a mechanical joint to prevent damage to the joint. One obvious application is enhancing the safety of human joints during athletic events. For ...
