    • Micro-mechanical testing of advanced ceramics: tools, procedures and first results 

      Camposilvan, Erik; Jiménez Piqué, Emilio; Anglada Gomila, Marcos Juan (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2013)
      Conference report
      Restricted access - publisher's policy
      Micro-mechanical testing has lately become a more accessible tool for understanding deformation, strengthening and failure mechanisms at small scales. It has been found that the often considered intrinsic or “intensive” ...

    • Micropillar compression inside zirconia degraded layer 

      Camposilvan, Erik; Anglada Gomila, Marcos Juan (Elsevier, 2015-11-01)
      Article
      Open Access
      In the dental field, Yttria-doped Tetragonal Polycrystalline Zirconia (Y-TZP) plays an important role due to its high mechanical properties, good aesthetics and bio-inert behavior. Surface mechanical properties are crucial ...
    • Revealing crack profiles in polycrystalline tetragonal zirconia by ageing 

      García Marro, Fernando; Camposilvan, Erik; Anglada Gomila, Marcos Juan (Elsevier, 2012-07)
      Article
      Restricted access - publisher's policy
      Exposure to hot water vapour is shown to be useful for staining indentation crack profiles in doped zirconia polycrystals. This is illustrated here in 3Y-TZP with two different grain sizes, for which Vickers indentation ...
    • Size and plasticity effects in zirconia micropillars compression 

      Camposilvan, Erik; Anglada Gomila, Marcos Juan (2016-01-15)
      Article
      Open Access
      The micropillar compression technique has shown the potential for activating the brittle-to-ductile transition in ceramic monocrystals when testing reduced volumes. In this work, the role of size is studied by comparing ...
