      Maspoch, Maria Lluïsa; Franco Urquiza, Edgar A.; Gamez-Perez, Jose; Sánchez Soto, Miguel; Velasco, José Ignacio; Santana Pérez, Orlando Onofre; Martínez Benazat, Antonio Universidad Simón Bolívar (2010)
      The Essential Work of Fracture (EWF) technique has been used for the ductile materials characterization, where yielding phenomenon occurs before crack propagation. The EWF method characterizes the post-yielding ...

      Gamez-Perez, Jose; Velázquez Infante, Julio César; Franco Urquiza, Edgar A.; Pagès, Pere; Carrasco, Félix; Santana Pérez, Orlando Onofre; Maspoch, Maria Lluïsa BME-PT (2011)
      The effect of a quenching treatment applied on heated cast sheet extruded films of two poly(lactic acid) (PLA) commercial grades, with different optical purities, was studied. The thermal and mechanical properties of the ...

      Maspoch, Maria Lluïsa; Franco Urquiza, Edgar A.; Gamez-Perez, Jose; Santana Pérez, Orlando Onofre; Sánchez Soto, Miguel Wiley (2009)
      BACKGROUND: Ethylene–(vinyl alcohol) (EVOH) copolymer/organo‐modified montmorillonite (OMMT) composites were investigated. Composites with two different percentages by weight of OMMT were prepared using a melt‐extrusion ...
