      In this study a FETI: Finite Element Tearing and Interconnecting [1] technique is adopted and exploited for the efficient and accurate modeling of softening materials such as concrete and rock. A fie scale analysis in which ...

    • FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides 

      Tarragó Cifre, Jose María; Jiménez Piqué, Emilio; Schneider, Ludwig; Casellas Padró, Daniel; Torres, Y.; Llanes Pitarch, Luis Miguel (2015-10-01)
      Article
      Accés obert
      Exceptional fracture toughness levels exhibited by WC-Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development ...

    • Fracture toughness of cemented carbides: Testing method and microstructural effects 

      Sheikh, Saad; M'Saoubi, Rachid; Flasar, Petr; Schwind, Martin; Persson, Tomas; Yang, Jing; Llanes Pitarch, Luis Miguel (2015-03-01)
      Article
      Accés obert
      Fracture toughness is one the most important parameters for design applications and performance assessment of WC-Co cemented carbides (hardmetals). Different from hardness, fracture toughness is commonly a property more ...
