Elastic property prediction of long fiber composites using a uniform mesh finite element method
(University of Missouri--Columbia, 2008)
This research numerically evaluates elastic non-isotropic material properties of fiber reinforced composite materials. Calculations are performed with a finite element mesh composed of a uniform array of three dimensional ...
Using feedback linearization to alter the performance of multiple linear hydraulic-actuators powered by the same pump
(University of Missouri--Columbia, 2020)
-actuators with both actuators being powered by the same pump. This research uses two open-centered 4-way valves to control the displacement of the two hydraulic actuators for a wheel loader implement system, based upon an input command from the operator who is modeled...
Numerical study of self-assembly of granular and colloidal particles
(University of Missouri--Columbia, 2021)
Self-assembly of granular materials and colloids are studied using several different computational methods such as Discrete Element Method (DEM), Smoothed Particle Hydrodynamics (SPH) method, finite volume Volume of Fluid ...
Theoretical and experimental investigation of oscillating heat pipes
(University of Missouri--Columbia, 2006)
A mathematical model describing the oscillation characteristics of slug flow in a capillary tube is presented. The model considers the vapor bubble as the gas spring for the oscillating motions in a capillary tube including ...
Development of acoustic metamaterials for efficient sound control noise mitigation
(University of Missouri--Columbia, 2021)
Acoustic metamaterials have been studied intensively recently since they can expose unnatural-born properties, potentially breaking the capacity limits of conventional acoustic materials. Since these interesting properties ...
