    • Coupled thermoelastic simulation of nanovoid cavitation by dislocation emission at finite temperature 

      Ponga, M.; Ortiz, M.; Ariza, M.P. (CIMNE, 2013)
      Conference report
      Open Access
      In this work we study the early onset of void growth by dislocation emission at finite temperature in single crystal of copper under uniaxial loading conditions using the HotQC method. The results provide a detailed ...
    • Finite-temperature nanovoid deformation in copper under tension 

      Ariza, M.P.; Ponga, M.; Romero, I.; Ortiz, M. (CIMNE, 2011)
      Conference report
      Open Access
      Tensile failure of metals often occurs through void nucleation, growth and coalescence. In high-purity metals, void nucleation often operates at the nanoscale and is followed by plastic cavitation when the void attains the ...
    • Thermomechanical study of nanovoid cavitation in aluminium 

      Ariza, M. P.; Ponga, M.; Ortiz, M. (CIMNE, 2013)
      Conference report
      Open Access
      Defects such as vacancies and nanovoids are known to drastically modify the structural state of materials. Void nucleation, growth and coalescence are important micromechanical mechanisms underlying ductile crack growth ...
