      Artús, Pau; Dürsteter, Juan Carlos; Martínez Benasat, Antonio; Segovia, Angélica (2007-03-21)
      Article
      Accés restringit per política de l'editorial
      La importancia que han adquirido polímeros orgánicos termoestables en el campo de la óptica oftálmica ha provocado una sustitución casi completa de los materiales inorgánicos tradicionales como el vidrio. La resina comercial ...

    • Effect of specimen notch quality on the essential work of fracture of ductile polymer films 

      Martínez Benasat, Antonio; León, Noel; Segovia, Angélica; Cailloux, Jonathan; Martínez, Paris (2017-06-07)
      Article
      Accés obert
      The essential work of fracture approach has been employed to analyse the effect of notch sharpening on the fracture toughness of a semicrystalline multiphase ethylene-propylene block copolymer. Double edge notched tension ...
