Effect of Body Forces Due To Aircraft Acceleration on Ventilation Airflow and Contaminant Dispersion in Passenger Aircraft Cabins
Numerical simulations for the effect of body forces due to aircraft acceleration on the airflow and contaminant dispersion in a model for a passenger aircraft cabin are performed in this study. It was found that those body ...
Development And Validation Of A Numerical Model For Vibration Of Power Lines
Modal testing is being investigated as a means of non-destructive evaluation of wooden utility pole strength. In order to understand the effects of conductors on the dynamics of the poles, a numerically efficient model ...
Effect Of Additives On Cutting Temperature Of Glass Fibers Reinforced Polymers
Composites are abrasive materials that generate heat during machining operations. This heat generates thermal damage locally and may severely alter the mechanical properties of the components if it exceeds the glass ...
Predicting The Consumption Speed Of A Premixed Flame Subjected To An Unsteady Stretch Rate
The stretched laminar flame model provides a convenient approach to embed realistic chemical kinetics when simulating turbulent premixed flames. When positive-only periodic strain rates are applied to a laminar flame there ...
Buckling And Post Buckling Behavior For Unsymmetrical Laminates Part II: Stability Characteristics
This is the second of two companion papers that examine the elastic buckling and post buckling behavior of unsymmetric cross-ply laminates. The existence of geometric imperfection and thermal mismatch between plies result ...
Vortex-Induced Vibrations Of A Low-Tension Cable-Sheave System Modeled Using Nonlinear Finite Elements
This work presents a finite element model of a cablesheave system constructed to model cable vibrations due to vortex shedding in low-tension cases. The study assesses the potential for vortex shedding to lead to detachment ...
Gradient Elasticity Modelling For The Analysis Of Fiber Composites With Fiber Resistant To Flexure
A model for the deformation of an elastic solid reinforced by embedded fibers is presented in which elastic resistance of the fibers to bending is incorporated. We developed the equilibrium equations and necessary boundary ...
Thermal Conductivity Of Advanced Architected Cellular Materials
Convergence Control For Topology Optimization
Proportional-Integral-Derivative (PID) control theory is applied to the evolutionary rate of the Bi-Directional Evolutionary Structural Optimization (BESO) method to control aspects of the convergence such as the rise time, ...
The Influence of Powder Size and Packing Density on the Temperature Distribution in Selective Laser Melting
Metal powder properties in Selective Laser Melting (SLM) is among one of the most important factors when implementing new alloy developments for the equipment. In fact, not all commercially available metal powder alloys ...
