Composite failure criterion - probabilistic formulation and geometric interpretation.
(Monterey, California. Naval Postgraduate School, 1988-12)
The objective of this investigation is to derive the reliability and the associated probabilistic failure criterion for composite materials under combined stress. In the analytical derivation, the concept of joint ...
Flow visualization of the airwake around a model of a DD-963 class destroyer in a simulated atmospheric boundary layer
This study is part of a longer-term project to map the airwakes of model ships for scaling to full size and use in helicopter simulators to provide an alternative to at-sea dynamic interface testing utilizing the Naval ...
The age hardening response of thermomechanically processed Al-Mg-Li alloys
Four Al-Mg-Li alloys of compositions (weight percent) in the ranges of 6-8% Mg, 0.5-2% Li and 0.15-0.25% Zr were hot forged and warm rolled (thermo-mechanically processed) to achieve a microstructure suitable for ...
The effects of torque response and time delay on rotorcraft vertical axis handling qualities.
Research was conducted in support of updating the U. S. military handling qualities specification, MIL-H-8501A. The effects of torque response and time delay on rotorcraft vertical axis handling qualities were investigated ...
Effect of fiber diameter on the reliability of composites - Automated laser diffraction implementation
Composite failures are microscopically sequential and locally redundant. As a result, a composite structure reliability and its strength dependency on geometric size is intimately dependent on the statistics of fiber ...
Flow visualization of the airwake of an oscillating generic ship model
An experimental flow visualization study was done on an oscillating generic ship model in the Low Speed Wind Tunnel Facility at the Naval Postgraduate School in Monterey, California. The purpose was to visually analyze ...
On analysis of viscoelastic structures.
This study is to understand the effects of nonlinear behavior of structures using a finite element method. The nonlinear behavior equations are derived from equations of motion and constitutive equations. The basic theory ...
Study of electrostatic modulation of fuel sprays to enhance combustion performance in an aviation gas turbine.
The influence of electrostatic and electrohydrodynamic charging on hydrocarbon fuel spray patterns and droplet atomization has been investigated. Research was performed in a combustion environment with an Allison T-56 ...
Particle sizing in a solid propellant rocket motor using a light scattering technique
Research was conducted to determine particle sizes across the nozzle of a small solid propellant rocket motor. Particle size was determined using light scattering techniques . The present optical components limit the lower ...
Transonic compressor blade tip flow visualization on a water table
The shock structure at the tip of a transonic compressor rotor was investigated on a water table. A four bladed cascade model was used and the wave pattern was examined at variable incidence, flow turning angles and ...
