Johansson, Alva January 2017 (has links)
This project explores the dimensional relationship between body and dress through using features of corsetry. Where is the garment tight? Where do we place volume and where do we show skin? This project addresses these questions and the construction of dress through broadening the concept of corsetry. With the vision to improve the relationship between body and dress through exploring new methods for an existing technique. Searching for alternative construction techniques in dress which enhances the circular relationship between body, dress and form. By exploring new working methods that includes the body in the process of constructing garments, the corsetry tools has been used to investigate how the garment stays on the body in terms of how we tighten it to the body and by that also give the garment its shape. The project is practice based and built on concrete experiments. The relationship between body, fabric and form has been explored through working hands on with the material on the own body. The design method was developed in the beginning of the project. Further, it was carried out through using rectangular and tube shaped fabrics together with features of corsetry, mainly focusing on eyelets and lacing. Resulting in both a new method for an existing technique, as well as a result that expresses new possibilities in the composition of the dressed body. It also proposes alternative ways of constructing and wearing garments, where the body and the garment work together.

Model Validation for a Steel Deck Truss Bridge over the New River

Hickey, Lucas James 26 May 2008 (has links)
This thesis presents the methods utilized to model a steel deck truss bridge over the New River in Hillsville, Virginia. These methods were evaluated by comparing analytical results with data recorded from 14 members during live load testing. The research presented herein is part of a larger endeavor to understand the structural behavior and collapse mechanism of the erstwhile I-35W bridge in Minneapolis, MN. Objectives accomplished toward this end include investigation of lacing effects on built up member strain detection, live load testing of a steel truss bridge, and evaluating modeling techniques in comparison to recorded data. Before any live load testing could be performed, it was necessary to confirm an acceptable strain gage layout for measuring member strains. The effect of riveted lacing in built-up members was investigated by constructing a two-thirds mockup of a typical bridge member. The mockup was then instrumented with strain gages and subjected to known strains in order to determine the most effective strain gage arrangement. Testing analysis concluded that for a built up member consisting of laced channels, one strain gage installed on the middle of the extreme fiber of each channel's flanges was sufficient. Thus, laced members on the bridge were mounted with four strain gages each. Data from live loads were obtained by loading two trucks to 25 tons each. Trucks were positioned at eight locations on the bridge in four different relative truck positions. Data were recorded continuously and reduced to member forces for model validation comparisons. Deflections at selected truss nodes were also recorded for model validation purposes. The model validation process began by developing four simple truss models, each reflecting different expected restraint conditions, in the hopes of bracketing data from recorded results. Models were refined to frames, and then frames including floor beams and stringers for greater accuracy. The final, most accurate model was selected and used for a failure analysis. This model showed where the minimum amount of load could be applied in order to learn about the bridge's failure behavior, for a test to be conducted at a later time. / Master of Science

Defining a Model for Tool Consumption Rate on Asphalt Reclamation Machines

Taylor, Matthew H. 30 November 2006 (has links) (PDF)
Asphalt and concrete reclamation machines are used to cut roadways when a repair is required. The performance of these machines can affect the quality of road repairs, and cost/profitability for both contractors and governments. We believe that several performance characteristics in reclamation machines are governed by the placement and pattern of cutting picks on the cutter head. Previous studies, focused on mining and excavation applications, have shown strong correlation between placement and wear. The following study employs a screening experiment (observational study) to find significant contributors to tool wear, in applications of asphalt milling or reclamation. We have found that picks fail by two primary modes: tip breakage, and body abrasive wear. Results indicate that the circumferential spacing of a bit, relative to neighboring bits, has the strongest effect on tip breakage. We have also shown that bit skew angle has a large positive effect on body abrasive wear.
