Discrete Damage Mechanics Applied To Transverse Matrix Cracking
<p>A constitutive model to predict the stiffness and coefficient of thermal expansion (CTE) reduction due to transverse matrix cracking in laminated composite structures is implemented as a user subroutine in Abaqus. The assumptions of the model are a symmetric laminate under in-plane loads and …

Optimal control with Kane Mechanics applied to a hybrid power split transmission
… work describes a method based on the Kane Mechanics to derive the state space equation for modelling and controlling a mechatronic system such as a hybrid transmission. The hybrid powertrain components, especially the dynamic behaviour for controlling a power split transmission are …

Fracture mechanics of volcanic eruptions
… by a failure model based on fundamental fracture mechanics, applied to a volcanic setting. In addition to the time series of earthquake activity, statistical measures such as seismic b-value are also analysed and compared with corresponding data from the field and laboratory studies. A greater …

Analysis and fabrication of paraboloidal CFRP sandwich mirrors.
… and low weight. The proposed replication method applied an interface layer between face and surface coat to eliminate print-through problems. Many important goals have been realized in those mirror samples with optical laser interferometer testing. These include the figure RMS error less than 2 …

A System for Measuring the Lift and Drag Forces of a Spinning Golf Ball Held Fixed Within a Wind Tunnel
A system was designed, built and tested in order to test the aerodynamic properties of a standard golf ball in a wind tunnel manufactured by ELD, Inc. model 406(B). The system consists of a rotating shaft, on which the golf ball is attached, connected to a two-axis force transducer. Additionally, …

Foundations for Finite-State Modelling of a Two-Dimensional Airfoil that Reverses Direction
<p>Current 3-D finite-state wake models are incapable of simulating a maneuver in which the sign of the free-stream velocity changes direction and the rotor enters its own wake -- as might occur in the case of a helicopter which ascends and then descends. It is the purpose of this work to create a …

Energy Harvesting from the Vortex-Induced Vibrations of Bluff Body Oscillators
<p>Vortex-induced vibration (VIV) of bluff bodies provides an effective mechanism for harvesting energy from fluid flows. Yet, the complex fluid-structure interactions governing vibration amplitude, synchronization, and energy transfer in single and coupled oscillators remain only partially …

Pressurization-induced Failure of Deforming Lava Domes: Theory, Experiment, and Application
Eruptions of lava domes are typically characterized as volatile-poor relative to explosive eruptions; however, the transport and storage of gases within lava domes plays a critical role in dome stability and explosivity as well as behavior of the magmatic system overall. Theoretical, experimental, …

The Varied Thermal Response of Magnetic Iron-Oxide Nanoparticles During Induction Heating in Liquid and Solid-Liquid Phase Change Mediums
<p>This study investigates the induction heating response of uncapped iron oxide nanoparticles sonically dispersed as a nanofluid and mechanically distributed in solid phase change materials. The nanoparticles examined have a mean diameter of 14.42 nm and are magnetically heated in an alternating …

High Order Explicit Semi-Lagrangian Method for the Solution of Lagrangian Transport and Stochastic Differential Equations
<p>A semi-Lagrangian method is developed for the solution of Lagrangian transport equations and stochastic differential equations that is consistent with Discontinuous Spectral Element Method (DSEM) approximations of Eulerian conservation laws. The method extends the favorable properties of DSEM …
