• Upper bound solutions of ring compression test 

      Martín-Fernández, Francisco de Sales; Sevilla-Hurtado, Lorenzo; Camacho, Ana; Sebastián, Miguel Ángel (2013-07-04)
      El presente trabajo aborda una particularización del proceso de forja, estudiando la deformación de un anillo. El conformado plástico se realiza mediante el empleo del Teorema del Límite Superior y siguiendo el modelo de ...
    • The Upper Bound Theorem in forging processes: Model of Triangular Rigid Zones on parts with horizontal symmetry 

      Martín-Fernández, Francisco de Sales; Cañero Nieto, Juan Miguel; Martin-Sanchez, Maria Jesus; Maldonado, Diego (2019-07-10)
      The analysis to determine the necessary forces with which to achieve a plastic deformation in metallic materials, in particular, in forging processes and under conditions of plain strain, has been raised over the years ...
    • Use of additive manufacturing on models for sand casting process 

      Martín Béjar, Sergio; Bermudo Gamboa, Carolina; Trujillo Vilches, Francisco Javier; Sevilla-Hurtado, Lorenzo (Universidad Politécnica de Cartagena, 2018-06)
      Casting is a forming process based on material pouring in liquid state. Heat is applied to melt the material from its solid state and pour it in a mold previously constructed to obtain the desired shape after letting it ...
