Development Of Ultra-high Temperature Material Characterization Capabilities Using Digital Image Correlation Analysis
(Aerospace Engineering, 2011-10-11)
Ultra-high temperature deformation measurements are required to characterize the thermo-mechanical response of material systems for thermal protection systems for aerospace applications. The use of conventional surface-contacting ...
Airfoil-shaped Extension-twist-coupled Composite Star-beams For Rotor Blade Tip Applications
(Aerospace Engineering, 2011-10-11)
Rotorcraft blade tips provide the most effective region for aerodynamic control. Rotor blade airloads are proportional to dynamic pressure and as a consequence are typically the highest in the distal blade tip region. ...
Algebraic Solution To The Planar Rigid Body Impact Problem
(Mechanical Engineering, 2011-07-14)
For systems of rigid bodies that undergo impacts, a series of closed-form equations are developed to solve for post-impact velocities which simulate a real-world (energy-consistent) interaction. The analysis is based in ...
Hybrid Dynamic Simulation For Performance Optimization Of Legged Mechanisms
(Mechanical Engineering, 2011-07-14)
Agile locomotion is needed for mobile robots to efficiently navigate challenging terrain. The ability of an agile legged mobile robot to abruptly change trajectory allows it toquickly react to obstacles and successfully ...
Simulation Of Indeterminate Multi-point Impact And Contact With Friction
(Mechanical Engineering, 2011-03-03)
This work presents a method for determining the post-impact behavior of a rigid-body undergoing simultaneous, multiple impacts with friction. A discrete algebraic model is used with an event-driven function which finds ...
Computational Model For Transient And Steady State Analysis Of A 1-dimensional Auto-thermal Reformer
(Mechanical Engineering, 2011-03-03)
This study presents a 1-dimensional mathematical model of steam reformer to be used with high temperature solid oxide fuel cell (SOFC). Steam reforming (SR) is widely used in industries to produce hydrogen from hydrocarbons. ...
Nonlinear Finite Element Analysis Of Columns
(Aerospace Engineering, 2011-07-14)
