Title: A discrete element approach to predicting the uniaxial compressive response of plain concrete
Author: Tannu, Nakul
Date Created: 2017
Subjects--Topical: Mechanical engineering
Description: Discrete element method (DEM) has become the method of choice for modeling the mechanical response of materials with granular structure. The method consists of representing the material as a collection of particles that interact with each other by...

Title: FINITE ELEMENT STUDIES OF ORTHOGONAL MACHINING OF ALUMINUM ALLOY A2024-T351
Author: Patel, Jaimeen
Date Created: 2018
Subjects--Topical: Mechanical engineering, Mechanics
Description: In this work, a new machining model using the commercial finite element software ABAQUS is developed. The model regards material separation, chip serration and breakage as ductile fracture processes where energy is required to form new surfaces. T...

Title: Geotechnical Controls on Organo-Silane Modification of Soils and Coal Combustion Fly Ash
Author: Keatts, Matthew
Date Created: 2014
Subjects--Topical: Civil engineering, Geotechnical engineering
Description: Organo-silane (OS) surface modification works by chemically altering the surface of silica based materials and rendering them hydrophobic (waterproof). Limited research is present in the literature addressing the use of OS modified soils as an inf...

Title: LABORATORY EVALUATION OF THE UNCONFINED COMPRESSION STRENGTH OF POLYMERIC FIBER REINFORCED SOILS
Author: Kral, Robert
Date Created: 2014
Subjects--Topical: Civil engineering, Soil science, Geotechnical engineering
Description: Geosynthetic fiber reinforced soil can be used to remediate weak, near-surface soils. The purpose of this study was to determine the impact that the geofibers had on the unconfined compressive strength (UCS) of various soil types. To distinguish t...

Title: Puerto Rico Grid Resilience Assessment Using Binomial Analysis Following Hurricane Maria Considering Storm Effects
Author: Ng, Yenki
Date Created: 2019
Subjects--Topical: Civil engineering
Description: Hurricane Maria was proven to be a very devastating storm in recent history. Ranked as the third costliest storm in the United States, Maria accumulated up to $90 billion in damages and accounted for at least 3,000 deaths. These deaths were primar...

Title: SYNTHESIS AND REACTIVITY STUDIES OF METAL CARBONYL COMPLEXES WITH PYRIDINE/THIONE MIXED-DONOR LIGANDS
Author: Oian, Casey
Date Created: 2015
Subjects--Topical: Chemistry
Description: A new synthetic route to o (mercaptoimidazolyl)pyridine ligands (R = Me, Bun) through a neutral intermediate o (imidazolyl)pyridine (o-impy) has been developed. The n-butyl-substituted ligand shows improved solubility in organic solvents. The alky...

Title: Slope Stability Analysis of Embankment Fill Material from North Carolina Coastal Region
Author: McGovern, Ashley
Date Created: 2016
Subjects--Topical: Civil engineering, Geotechnical engineering
Description: This research involved a comprehensive experimental program was carried out to study compaction characteristics and associated engineering properties of test soils from three actual NCDOT highway projects located within the coastal geologic region...

Title: Synthesis and Reactivity of N-Heterocyclic Chalcogenone Complexes of Copper and Silver
Author: Allen, Alexander
Date Created: 2018
Subjects--Topical: Chemistry, Inorganic, Chemistry, Organic, Analytical chemistry
Description: This presentation outlines the synthesis and characterization of several unusual two-coordinate copper(I) and silver(I) complexes supported by bulky N-heterocyclic thione (NHT) and selone (NHSe) ligands. More specifically, copper(I) complexes of t...
