    • A plasticity model for simulation of industrial powder compaction processes 

      Oliver Olivella, Xavier; Oller Martínez, Sergio Horacio; Cante Terán, Juan Carlos (1996-08)
      Article
      Accés restringit per política de l'editorial
      A constitutive model, based on large strain plasticity, for simulation of industrial powder compaction processes is presented. The elastic response is stated in terms of a hyperelastic model based on a hookean elastic free ...

    • Finite element modelling of ejection cracks in powder metallurgy die compaction processes: case study 

      Hernández Ortega, Joaquín Alberto; Oliver Olivella, Xavier; Cante Terán, Juan Carlos; Weyler Pérez, Rafael (2012)
      Article
      Accés obert
      To date, the modelling of crack formation during the ejection stage in powder metallurgy die compaction processes has fallen outside the scope of conventional finite element studies on this process. In this paper, we attempt ...

    • Ligantes base agua para pulvimetalurgia 

      Monterde Gascón, María Carmen (Universitat Politècnica de Catalunya, 2010-02)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      La problemática de salud laboral y medioambiental que presenta el tricloroetileno (TCE: R40, 45, 52/53) ha condicionado en gran medida los esfuerzos realizados para su sustitución. Uno de los procesos afectados es la ...

    • On numerical simulation of powder compaction process: powder transfer modelling and characterisation 

      Cante Terán, Juan Carlos; Oliver Olivella, Xavier; Gonzalez, C; Calero Martínez, José Antonio; Benitez, F (2005-08)
      Article
      Accés obert
      A numerical model for the powder transfer stage in powder metallurgy cold compaction processes, and the corresponding material characterisation procedure, are proposed. They have been designed on the basis of the following ...
