Along with the interference fit parameters, the consideration of materials is mentioned as well.
Principally, the selection of materials for an interference fit is usually a consideration of both shaft and hub, as a pair of materials.
A typical study of different mating materials in interference fitted assemblies was carried out by Udupa and Sogalad, the paper presented the experimental results of different mating pairs of materials [9].

Subject "the Research and Application of Life Cycle Assessment Technology to the Building Materials for Building Engineering in Typical Regions" of the National Science & Technology Pillar Program during the Twelfth Five-year Plan Period (No.: 2011BAJ04B06) Introduction As the policies for building energy efficiency has been fully implemented and the green building action widely carried out, the technology for the assessing and verifying green building materials is vital and needs to be established as soon as possible.
At present, the study on life cycle assessment for thermal insulation materials [8,9] is rarely reported in China.
This paper has performed the life cycle assessment on three most widely used thermal insulation materials (namely, the polystyrene board, the polyurethane board and rock wool board) in the current domestic building engineering based on the LCA method, combining the characteristics of the employing of such materials in different regions, and is aimed to illustrate the basic information of the life cycle environmental load of thermal insulation materials in this industry and to provide data support to the establishment of localized LCA database for thermal insulation materials and the assessment of green building materials.

Data on operation time, material handling time are collected, analyzed and discussed.
Introduction Even though the light materials are widely used in the modern world of manufacturing industries, sheet metals are still mostly used in making of various components in automobiles, aircrafts, home appliances etc.
In this study, better manufacturing method is used to improve the productivity by reducing the material handling time.
