Abstract:

We study the problem of packing spheres of different radii into a rigid container. The spheres are packed as densely as possible so they neither overlap nor cross the boundaries of the container. The packed spheres are then meshed in preparation for finite element analysis. The spheres are meshed individually (separately) without taking care of the contact surface between spheres or containers wall. The last step is the hydrostatic pressing of the spheres made of elastic-plastic materials and with simplified contact conditions. Such simulations are of interest to the metallurgist because they

Abstract:

Micro-Electro-Mechanical-System (MEMS) and Nanotechnology have both received significant attention in recent years due to their potential for manufacturing highly miniaturised devices which consume less raw materials and energy in their production, and function with greater efficiency, speed, and reliability. The first project described in this thesis concerns the development of a novel, low cost, contamination-free nanofabrication system. This system is enabled by a MEMS-based device which has the dual functions of a high-precision AFM (Atomic Force Microscope) cantilever probe and a shadow m

Promising techniques such as micro-stereolithography (MSL) are opening up practical potential for exploiting new ideas for specialized polymer-based Micro-Electromechanical systems (MEMS) through small-batch production. As the field matures and grows, substantial research and commercial development demands better understanding of mechanical properties of MEMS materials to fully explore the potential of this technology. Bulk properties derived from conventional testing of large specimens (at 10 mm order) cannot be trusted. However, small-scale specimens (less than 1 mm) introduce major challeng

The nanoindentation or indenter testing technique (ITT) is a functional and fast technique that can give us a lot of information about the mechanical properties of different materials at nanometric scale, from soft to brittle materials. The principle of the technique is the evaluation of the response of a material to an applied load. In a composite material, if the size of the residual imprint resulting from a certain load is lower than the size of the studied phase, then it is possible to determine its mechanical properties, and therefore its contribution to the global mechanical properties o

The seismically induced interface friction capacity of piled foundations is a function of the soil-pile interface friction, the relative stiffness of the pile and the soil and the volume changes in the soil adjacent to the pile which affect the strength and stiffness of the soil. In order to fully understand this interface it is necessary to study the behaviour at the micro level which is possible with Discrete Element Modelling. A 2D DEM model was developed that simulated a section of an inflexible pile in a coarse grained soil that was subject to cyclic shear load. The model had to be repres

The utilization of micro-scale technologies is limited by the speed of their manufacture. Micro-milling is one particular technology used to manufacture micro-scale parts which could benefit extensively from an increase in throughput. Micro-milling involves a rotating cutter slightly thicker than a human hair removing material while spinning at speeds often over one hundred thousand revolutions per minute. An obvious solution to the throughput bottleneck is to move current micro-mills faster using existing technology; however, simply increasing the operational speed of existing micro-mills wi

Together with other unique properties of polymers, such as, low density, easy processability, good biocompatibility, and electrical insulation, the crystalline fibers in micro/nano scale can be used in a broad range of applicati

Narrow-band sensitivity is obtained by optical resonance phenomena within a Fabry-Perot (FP) cavity, that is created by two Bragg reflectors and is monolithically integrated with an HgCdTe IR detector.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2004.<br>Includes bibliographical references (p. 77-80).<br>A micro-fabricated solid oxide fuel cell is currently being designed by the Micro-chemical Power Team(funded under the Multidisciplinary University Research Initiative(MURI) Research Program). In the current design a plate structure vital to power generation is exposed to harsh thermal operation conditions, making it susceptible to structural failure. This thesis investigates the mechanisms of its structural failure, develops tools and models
