Shape Memory Alloy and Micro-Motor Activated High Pressure Optical Cell for Bio-Physical Studies

This paper details the design and testing of a new shape memory alloy-based actuator for high-pressure optical cells. The actuator is developed to allow for the mixing and stirring of solutions under pressure without obstructing optical observation.

Load Impact on Railway Track Due to Unsupported Sleepers

A Lundqvist, T Dahlberg

This paper presents a computer model by which the dynamic train/track interaction can be simulated. The influence of one or several voided sleepers on the train/track interaction force and on the track dynamics is investigated. Track settlement due to hanging sleeper(s) is discussed.

Multigrid Method for Solving Three-Dimensional Implicit Solid Mechanics Problems

This paper describes a parallel multigrid method for solid mechanics problems on unstructured finite element meshes using a distributed memory model with MPI and Fortran90. The implementation shows good speedup and scalability on several high-performance computers, although the floating-point performance is below the machines' peak capabilities.

Ship Concept Exploration and Development Ship Concept Exploration and Development

Virginia Tech AOE

This presentation describes a systems engineering method for early-stage naval ship design. It uses multi-objective optimization to balance cost, risk, and effectiveness. The process integrates Computational Fluid Dynamics (CFD) to provide key predictions for a ship's hydrodynamic resistance and seakeeping, enabling a more data-driven approach to evaluating new designs.

BRIDGING THE GAP IN UNDERSTANDING BONE AT MULTIPLE LENGTH SCALES USING FLUID DYNAMICS

Eric James Anderson

This technical paper investigates the role of fluid flow in bone remodeling by employing computational fluid dynamics to bridge the knowledge gap between tissue-level and cellular-level understanding. It uses CFD models to predict mechanical forces and fluid parameters at the nano-micro scale, which are currently immeasurable through direct observation. The work also applies these findings to optimize in vitro cell flow devices and tissue engineering scaffolds.
