The effect of boundary conditions on the failure of thin plates subjected to impulsive loading

Bibliography: leaves 64-65.This report presents the results of an investigation into the effects of edge boundary conditions on the failure of thin plates subjected to impulsive loading. In previous investigations the discrepancy between experimental results and theoretical solutions and effects observed at the edges of deformed plates have brought the method of securing the plate into question. This investigation examines the effect of edge boundary conditions by comparing the results of previous experiments where the plates were secured by clamping - with experiments where the plates are built-in (integral) with their supports

Show me what you’ve got - the influence of combined sketching on idea generation in teams

The present study investigates the influence of common sketches on the idea generation process in early concept generation. Thirty-six teams of three design students were given a small task in which they were asked to come up with visualized ideas. In the control groups, team members sketched on an individual sheet of paper while working in a team. As expected , the teams sketching individually produced more in total and more diverse ideas. No difference was found between the quality and innovativeness of the ideas. Also according to the hypotheses, individually sketching teams elaborated less on their ideas and explained their own ideas more. THe teams did not differ in their satisfaction with the final result. The result suggest that common sketching did serve as a common ground in the group that leads to shared views and ideas. This, however, goes along with less productivity of ideas.Product Innovation ManagementIndustrial Design Engineerin

Community based design support

Different approaches of design methodology that have been developed throughout the history of the design methods movement have produced many insights into the structure of the design process (Alexander, 1964; Simon, 1969; Schön. 1983; Hubka and Eder, 1987; Pahl and Beitz. 1984; Roozenburg and Eekels, 1995). It seems however, that little of this accumulated knowledge is used in the daily practice of designing. The relation between design methodology and design practice is still weak (Cross, 1993; Achten et al. 2005). One reason might be that design methods are not addressing the designer’s needs. And thus are not supporting the designer, with a specific task, to solve the problem at hand. (Badke-Schaub et al. 2005) The aim of this research project was to develop a solution for this problem: the concept of Community Based Design Support (CBDS). This concept, inspired by the online community platforms that are emerging on the internet, enables the integration of a personal, contextual, social and dynamic dimension in design methodology Based on the CBDS model a software platform was designed: Designflow. A prototype was built to test if the concept of CBDS can provide designers with efficient and effective design support.Industrial Design Engineerin
