Summary

A great amount of material information and data are available on the web, either direct or indirect via software and database presentations. There are direct, accessfree online material like materials information, selection databases, and technical reference guides, and there are a great diversity of commercial materials databases which are accessible via numerous online hosts. With listings of these web-based sources for material property information, it is possible to compare information and to get a more overall view. The information available on Internet has been found to have many forms e.g.: software and databases, online reference guides, selection guides, journal prints or abstracts, technical papers and reports, educational hypertexts and simulation programs, glossaries and indexes, material (chemical compounds) safety sheets, guides to elements, and that information that might be procured through direct communication via for example news- and discussion groups. Short presentations and links to materials meta sites (meaning sites with additional often comprehensive links), as well as to materials databases are given. Special focus has been devoted to European material information systems. Databases are described including information on content, materials properties, database host, and access mode. In this work lists of many WWW-sites offering materials information have been established. Of these some have business emphasis and can be relevant for industry, while others can be interesting for people dealing with research or education. The purpose is to provide a good starting point for further search into specific subject areas on different types of materials; metals, plastics, ceramics and composites.

1. Introduction

On the Internet there are many pages with links concerning materials science & engineering; in fact many academic institutions and most organizations working within the area have one. There is a need to have a more comprehensive listing of web-based sources for material property information, and that is what this work should provide. There is a need for material information systems (MIS), both the manufacturing industry as well as the general research community are urging for this. Using the web implies many potential benefits such as; increased access; demos or full versions of MIS can be established so that potential users can decide whether the systems are useful for them. Awareness of existing MIS seems to be limited. Some types of systems seem to be developed over and over again without the general level being improved in comparison to that of past systems. This indicates that the communication between people working on MIS is not very extensive. Again this hampers the general development in the area. Internet offers well known opportunities: hypertext functionality; the benefits of having a variety of literature and data at one's disposal with the use of search engines, to have the text illustrated with highly visual aids as digitized video clips, animations, etc., to trace information otherwise hard to find, to test systems. News- and discussion groups are one of Internets great advantages, putting people across the world in contact to share their knowledge and procure new cognizance. Discussion forums like these should not be underestimated as sources for general and specified information for the entire materials community spanning from students to industry workers and researchers. Part of the information on materials properties on Internet is considered proprietary by its owners and providers and is available online only through commercial database vendors. Databases and software are provided against payment i.e. by subscription or through purchasing online. There are some very good examples of sites containing comprehensive access-free information though. Universities and educational institutions are promoted through licensing agreements with academic networks or consortia of libraries, and industrial networks exist for information sharing among collaborators brought together by similar directions in research and development (and not seldom by proximity, examples: the Sheffield Forgemasters Group of Companies, and the IRC in Polymer Science and Technology, both situated in England). The perhaps most useful (non-paid) information that utilizes Internet’s basic networking function to a full, is the kind of Registry features that intend to bring together the materials community in centralized web locations, pertaining to plastics, composites, ceramics, and other specific material groups or issues. Polymers DotCom, Composites Corner and the Composite Registry, the Ceramics Web, and Swiss Tribology Online. These collecting nodes provide an easy way to locate manufacturers, suppliers, university programmes, and all-round, relevant info. I have tried to collect web-sites that contain some form of information that is directly of interest for a casual visiter that is looking for hard facts about a specific material, or sites that have some kind of interesting and valuable software to offer. These sites are, naturally, often of commercial nature, or a form of advertising for the companys own product. Nevertheless they provide a valuable piece of information for the general materials community. And the people who established them should be credited.

2. Method

In collecting this material Internet has been scanned with the help of search engines, mainly Alta Vista. Key words have included: material(s) database and databank, combined with other key words such as steel, aluminium, polymers, ceramics, composites, properties, information, etc. Examples of key word combinations are: material information, database +steel, alumin*m, to cover both the European and the American spelling of the word, material* database -.com -.org -.edu -.gov, to search for non-American materials databases presented on the net, etc. Sites of organizations and societies of major influence in the area of materials science and engineering have been included, as well as sites covering different materials and subject specific areas. The focus has been on web documents describing materials databases and other systems having materials information, for example technical reference guides, and materials information and selection systems. The search results have been lists of materials sites which have been browsed through "node for node", eventually building up an image of the material information situation on Internet. Separate lists of the materials databases have been established. When searching for materials information different categories of sources are revealed, of which some are of clearly commercial nature while others can be shareware, informative sites (company and product information, etc.), or of guiding nature (meta sites, net libraries). These are described in the following chapter including examples of web sites. For each material category a brief description of contents of the web sites, as well as the task and main directions of major material institutions are provided, and with links to the specific web places. The information has been sorted according to either origin or type of information; meta sites, databases, educational material, online journals, organizations, etc. The different sub-headings specifying the source can sometimes be vague or overlap each other. Under the headline general information information that does not fit under any other description or has multiple functions is gathered. Special focus has been devoted to European material information systems, for databases and for other
material information systems (MIS). In many cases detailed information is listed, for example on a) content; material and compounds types covered, properties covered, completeness of information, b) availability; intended user groups and purpose of system, under development, pilot or commercial system, platform, and distribution (diskettes, CD-ROM, traditional on-line, Internet, etc.). In searching for material databases from European sources use has been made of the CODATA Register of Materials Database Managers, 1993 edition. For some databases of special interest, present in this booklet but not presented on the web, the database managers have been contacted by fax or phone to give further information. NEXT TOP
