Meaning Attribution

Materials in product design used to be selected based especially on manufacturability concerns and technical aspects such as strength, conductivity, elasticity, etc. Nowadays, the increasing recognition for more intangible issues like meaning attribution or creating emotions in product design made designers shift their focus towards the intangible aspects in their materials selection activity as well. In this research, we aim to concentrate particularly on attributing meanings to materials. It is crucial to realize that several aspects (function, use, context, user, etc.) can be effective in attributing meanings to materials and they should be taken into consideration during the selection process. In this paper, we focus intensively on one of these aspects: the effect of form on attributing meanings to materials. The paper consists of four related studies exploring how people associate some forms with some particular materials and weather form can be effective in changing these ascribed meanings, or not.

Recuperation is a means for increasing the efficiency of a simple-cycle gas turbine, allowing for heat transfer between the exhaust and compressor discharge gas streams to occur in a highly efficient, relatively compact package. The primary surface recuperator operates at high temperatures and gas pressures and is constructed from thin metal sections, presenting challenges for high temperature materials selection. This paper discusses a joint Solar Turbines-ATI Allegheny Ludlum project which was undertaken to address the issue of elevated temperature attack in the presence of high levels of water vapor and its relevance to alloys intended for use in primary surface recuperators. An overview of the alloy selection process will be presented, followed by a detailed study of the two most promising alloy candidates. Breakaway oxidation was mitigated by using alloys with higher nickel and chromium content, and oxide scale evaporation was controlled with selected minor element additions.

Abstract Selection of an appropriate sterilization modality requires an understanding of certain key aspects of the product under consideration. Primary aspects to be considered include understanding of the product's intended use and details of the product design. This article reviews these primary considerations for sterilization modality selection and demonstrates the sterilization modality selection process through several example case studies.

Capstone Design

ABSTRACTThe Capstone Design course in the Department of Mechanical Engineering at Northeastern University requires students to build a physical prototype by the end of the two semester sequence. Although students have long been required to take an introductory materials science course as part of their curriculum, there was concern that materials selection was a weakness in the design process. Beginning in Fall 2011, the CES Edupack materials selection software was introduced into the Capstone Design class. The current work means to investigate: 1) how to assess designs for effective materials selection 2) whether the new software was actually used by the student teams and 3) whether there was evidence of improved materials selection in the projects that occurred after the new software was introduced. Final capstone design reports from 10 previous terms were examined to look for evidence of systematic materials selection procedures and clear discussion of materials properties as the basis for selecting a material. References to the software were also noted. Results show that 24% of the groups used the CES Edupack software in the first three terms that the software was available. In addition, there was an increase in the number of groups that used a systematic selection process based on research into published materials properties rather than choosing materials based on rough experimentation or convenience. Finally, there has been an increase in the number of projects which consider or incorporate composites, high temperature alloys, and advanced polymers as the software has increased awareness of these options.
