  • Failure analysis of a fastener system and its analytical prediction 

    Ossa, E.A.; Paniagüa, M.A. (2009-01-01)
    This paper describes the failure analysis performed for a fastener system commonly used in civil construction. This system was manufactured using AISI-SAE 1045 steel and showed unusual sudden cracking while a preload was ...
  • Morphological and mechanical characteristics of rigid polyurethane foams 

    Restrepo-Zapata, N.C.; Ossa H., E.A.; Mejia, F.C. (2009-01-01)
    Cellular materials are formed by solid cells in a gaseous core. They exhibit good strength to mass ratio and they are used as insulators and as a core in sandwich composite manufacture. This work describes an extensive ...
  • Natural flexible armor as an inspirationfor body armor design 

    Alexander Ossa, E. (Soc. for the Advancement of Material and Process Engineering, 2015-05-21)
    Animals have developed different strategies to protect themselves from environmental and predatory threats. One of these strategies concerns with the development of natural flexible dermal armor, usually consisting of rigid ...
  • Microstructure and mechanical properties of fish scales from MegalopsAtlanticus 

    Gil, S.; Ossa, E. A. (IEEE, 2013-01-01)
    This work studies the microstructure and mechanical properties of fish scales from Tarpon fish (MegalopsAtlanticus) with cycloid scales. Mechanical properties of the scales were evaluated in uniaxial tension from three ...
