Materials selection in mechanical design

Materials selection in mechanical design

A novel materials-selection procedure has been developed and implemented in software. The procedure makes use of Materials Selection Charts: a new way of displaying material property data; and performance indices: combinations of material properties which govern performance. Optimisation methods are employed for simultaneous selection of both material and shape. INTRODUCTION The performance of ...

Materials Selection, Modeling and Mechanical Design

These lecture notes address materials and structures issues associated with the MIT Microfabricated gas turbine engine. An overview of the project and the performance goals is provided. These are translated into requirements for the materials and structural design. Particular emphasis is provided on the approaches taken to designing with brittle materials at low temperatures and designing with ...

Materials selection in the Life-Cycle Design process: a method to integrate mechanical and environmental performances in optimal choice

The choice of materials takes on strategic importance in design aimed at harmonising the performance characteristics and ecocompatibility of products in line with the Life-Cycle Design approach. The objective of the present study is the development of a systematic method which introduces environmental considerations in the selection of the materials used in components, meeting functional and pe...

Perceptual Scaling in Materials Selection for Concurrent Design

In this short paper, we describe the development of an adaptive design assistant to support and advise design team members when selecting materials for manufacture. Candidate proposals for materials are identified when the user subjectively rescales a similarity-based representation of materials. The approach taken seeks to acknowledge that personal decisions do not always appear rational and t...
