  • Comportamiento a la fractura de materiales para lentes oftálmicas 

    Artús, Pau; Dürsteter, Juan Carlos; Martínez Benasat, Antonio; Segovia, Angélica (2007-03-21)
    Article
    Restricted access - publisher's policy
    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 ...
  • Essential work of fracture analysis of the tearing of a ductile polymer film 

    Martínez Benasat, Antonio; Segovia, Angélica; Gamez Pérez, José; Maspoch Rulduà, Mª Lluïsa (2010-09)
    Article
    Restricted access - publisher's policy
    The fracture behaviour of a 0.5 mm thick ethylene-propylene block copolymer, previously evaluated using the essential work of fracture method, has been analyzed again in more detail, using different plots, allowing the ...
  • Fractura a velocidades de impacto en distintos grados de copolímeros de propileno-etileno 

    Martínez Benasat, Antonio; Segovia, Angélica; Illescas Fernandez, Silvia; Sánchez Soto, Miguel (2009-03-25)
    Conference lecture
    Open Access
    Se han inyectado probetas de 9 mm de espesor de dos copolímeros de propileno-etileno. A estos espesores estos copolímeros cumplen los requisitos de la LEFM. Se ha determinado KIC en un equipo de impacto pendular y se ...
  • Fracture behaviour of an EPBC film. Study of the relationships between J0 and EWF 

    Martínez Benasat, Antonio; Delgado, A; Segovia, Angélica; Sánchez Soto, Miguel; Salazar, Alicia (2010)
    Conference report
    Restricted access - publisher's policy
    The fracture behavior for a film of ethylene-propylene block copolymer has been studied applying the essential work of fracture method. Double-Edge Notch Tensile (DDENT) specimens were sharpened by two different techniques. ...
  • Influence of the notch sharpening on the fracture toughness of bulk ethylene-propylene block copolymers 

    Salazar, Alicia; Rodríguez, Jesús; Segovia, Angélica; Martínez Benasat, Antonio (2010-03-02)
    Article
    Restricted access - publisher's policy
    The effect of the notch sharpening procedure on the fracture toughness computed under linear-elastic and elastic-plastic conditions (at low and high loading rates, respectively) of a bulk ethylene–propylene block copolymer ...
