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 ...
متن کاملMechanical Failure in Microstructural Heterogeneous Materials
Various heterogeneous materials with multiple scales and multiple phases in the microstructure have been produced in the recent years. We consider a mechanical failure due to the initiation and propagation of cracks in places of high pore density in the microstructures. A multi–scale method based on the asymptotic homogenization theory together with the mesh superposition method (s-version of F...

15 صفحه اولMaterials 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 ...
