General Engineering


  • Efunda    (formulas, constants, properties)
    A handy source for formulas and constants with information pertaining to materials properties, processes and design.  Design content includes calculations for beams, stress transforms, and principle stress.  The content leans towards mechanical but is useful to all engineering disciplines.
  • EEVL – Engineering Section
    Provides links in Engineering, Mathematics and Computing. EEVL (Enhanced and Evaluated Virtual Library) is maintained by a team of information specialists from a number of universities and institutions in the UK.
  • GrayLIT Network
    Provides access to technical reports from the Dept. of Energy, Dept. of Defense, Environmental Protection Agency (EPA) and National Aeronautics and Space Administration (NASA). GrayLIT Network is the world’s most comprehensive portal to Federal “gray literature.”
  • MatWeb
    Consists of “a searchable database of material data sheets, including property information on thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, polyethylene and polypropylene; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus semiconductors, fibers, and other engineering materials”.
  • National Academies Press
    Engineering and technology books that can be read online FREE!
  • NASA Technical Reports Server (NTRS)
    Provides technical information from NASA, including research reports, journal articles, conference and meeting papers, technical videos, mission-related operational documents, and preliminary data. NTRS also collects scientific and technical information from sites external to NASA to broaden the scope of information available to users. These external sites include the Aeronautical Research Council (UK), the arXiv Physics e-Print Server, Biomed Central and the Energy Citation Database.
  • OSTI e-Prints
    Facilitates access to and use of scientific and technical e-prints on a wide range of research activities of interest to the Department of Energy.
