Robust bird-strike modeling using LS-DYNA
(2006)
Throughout this work, bird-strike events are studied using three approaches in LSDYNA: Lagrangian, Arbitrary Lagrange Eulerian (ALE), and Smooth Particle
Hydrodynamics (SPH). A simple one-dimensional beam centered impact ...
AFM studies on fractured surfaces of AF1410 steel and A7075-T6 aluminum alloy
(2006)
In the present research, atomic force microscopy (AFM) was used to characterize fracture surfaces of the AF1410, ultra-high strength steel, and a high strength AA7075-T6 aluminum alloy. Both materials are used by the U.S. ...
Preliminary performance study of Sherwood Regulator
(2006)
This is a Project of practical application directed to the liquefied petroleum gas industry at the University of Puerto Rico and the objectives of this project are to study the 800 JBC Sherwood Regulator performances and ...
Diseño asistido por internet para sistemas mecánicos - IAD
(2006)
In this work it’s desired to take advantage of the enormous amount of dispersed information available in the Internet that can be integrated into the automation of the mechanical design process. Technologies related to the ...
Flow and entropy characteristics around airfoils in subsonic and supersonic flows
(2006)
The presented research work analyzes numerically the flow characteristics such as density, pressure, and temperature at subsonic and supersonic speeds for flows past airfoils and explain their difference. Also, it analyzed ...
Time constant anomaly detection of thermocouples using transient data
(2006)
A specific methodology to detect anomalies in temperature sensors is developed
in this thesis. The strategy evaluates sensor faults or variations in the transient region
only by examining the signal produced by a ...
Design and characterization of passive wireless strain sensor
(2006)
In order to predict and avoid disasters due to the structure failure, reliable strain information is necessary to be monitored in real time. Existing strain sensing technologies offer outstanding performance in terms of ...
Fabrication and characterization of functionally graded Al/AlB2 matrix composites for high wear aerospace applications using centrifugal casting
(2006)
Functionally graded advanced composite materials contain reinforcement particles whose volume fraction varies continuously thereby bearing a non-uniform microstructure with continuously changing properties. Aluminum-based ...
