Finite Element Based Cross-Sectional Buckling Optimization for a Constant Area, Pinned-Pinned Composite Column
(2016-05-10)
In archery, dynamic buckling compromises the target accuracy of arrows. For both dynamic and quasi-static buckling, the buckling load depends on the cross-sectional area moment of inertia, which can be increased by modifying ...
FINITE ELEMENT BASED WEIGHT REDUCTION SUBJECT TO STABILITY CONSTRAINTS FOR AN AIRSHIP COMPOSITE DUCT
(2016-05-10)
The primary functions of High Altitude Long Endurance (HALE) airships are persistent observation and wide area direct line of sight communication. Traditional airships have an ellipsoidal type hull, which is characterized ...
A study of effect of bond length on bond strength using transient heat transfer analysis
(2018-08-17)
It is important to understand the mechanical properties of the bonding between the adjacent layers of 3D printed parts build by fused deposition modeling. The bonding process is highly nonlinear and depends on various ...
INFLUENCE OF RELATIVE DENSITY AND MICROSTRUCTURAL ANISOTROPY ON THE GLOBAL ELASTIC PROPERTIES OF CELLULAR STRUCTURES
(2017-05-05)
The favorable strength-to-weight ratio of cellular solids makes them ideal for structural applications. With the advent of additive manufacturing, the fabrication of complex cellular structures is becoming a reality. It ...
SURFACE ROUGHNESS FORMATION DURING TENSILE PLASTIC DEFORMATION OF NICKEL POLYCRYSTALS
(2018-09-10)
Understanding the formation of surface roughness could help better diagnose a metal component’s health and could potentially help in making better microstructure design decisions. Both of these, in turn, contribute to the ...
INVESTIGATION OF FIBER-REINFORCED CONCRETE CRACK WIDTH MEASUREMENT BY FINITE ELEMENT METHOD
(2016-12-21)
This study presents numerical and experimental investigations of flexural cracking, post-cracking strength, and fracture energy of the dry-cast synthetic fiber reinforced concrete (FRC). Notched and un-notched beams for ...
Study of SAC Solder Interconnect Parameters in Microelectronic Semiconductor Packaging and their Effects on Electromigration Failure Mechanisms
(2021-12-13)
As the shrinkage of electronic devices becomes more appealing, so do their high capacity and efficiency. This demand for ever-shrinking sizes of electronic devices follows the trend predicted by Moore’s Law. To achieve ...
Multi-mesh reduced-order basis method for finite element analysis
(2017-08-16)
Reduced order modeling of differential equations parametrized over a parameter space can be used to accelerate optimization and parameter estimation problems. The method of snapshots or reduced order basis is well established ...
Development of A New Joint System for A Circular-Shaped Infrastructure
(2017-04-28)
This dissertation focused on development of new carbon fiber joint systems for all types of underground gravity and sewer pipe systems. Specifically, the external CFRP wrap and, particularly, the carbon fiber reinforced ...
Developing A Geospatial Web Application for Transportation Geotechnical Asset Management
(2024-01-09)
**Please note that the full text is embargoed until 02/01/2025** Spatial data has become an increasingly important tool in geotechnical engineering, allowing for managing and analyzing large amounts of spatial data. In ...
