    • A unified non-linear energy dissipation-based plastic-damage model for cyclic loading 

      Cornejo Velázquez, Alejandro; Jiménez Reyes, Sergio; Barbu, Lucia Gratiela; Oller Martínez, Sergio Horacio; Oñate Ibáñez de Navarra, Eugenio (2022-10)
      Article
      Open Access
      A new energy-dissipation-based rate-independent constitutive law within the framework of elastoplasticity coupled with damage is proposed. With this methodology, the inelastic strains and the stiffness degradation exhibited ...

    • Analysis of post-tensioned structures by means of a constitutive serial-parallel rule of mixtures 

      Jiménez Reyes, Sergio (Universitat Politècnica de Catalunya, 2018-06-14)
      Master thesis
      Open Access
      The main purpose is to test a reliable method based on a three-dimensional (3D) finite-element (FE) model to simulate the constitutive behavior of reinforced concrete structures strengthened with post-tensioned tendons. ...

    • Analysis of the mock-up of a reactor containment building: comparison with experimental results 

      Jiménez Reyes, Sergio; Cornejo Velázquez, Alejandro; Barbu, Lucia Gratiela; Oller Martínez, Sergio Horacio; Barbat Barbat, Horia Alejandro (2020-04)
      Article
      Open Access
      The results of a predictive analysis of the mock-up of a reactor containment building, based on computer numerical simulation, are presented in this paper and compared with the results obtained in the context of the VeRCoRs ...

    • Failure pressure analysis of a nuclear reactor prestressed concrete containment building 

      Jiménez Reyes, Sergio; Cornejo Velázquez, Alejandro; Barbu, Lucia Gratiela; Barbat Barbat, Horia Alejandro; Oller Martínez, Sergio Horacio (Elsevier, 2021-06)
      Article
      Restricted access - publisher's policy
      The failure analysis of an existing and operational nuclear power plant reactor containment building subjected to an accident internal pressure is studied in this paper. The computation is based on the Finite Element Method ...

    • Numerical simulation of a rapid fatigue test of high Mn-TWIP steel via a high cycle fatigue constitutive law 

      Gonçalves Junior, Luis Antonio; Jiménez Reyes, Sergio; Cornejo Velázquez, Alejandro; Barbu, Lucia Gratiela; Parareda Oriol, Sergi; Casellas Padró, Daniel (2023-03)
      Article
      Open Access
      The generation of reliable data in the high cycle fatigue domain is crucial to support further metallurgic developments of fatigue optimized steel grades. Commonly employed for this aim, traditional standardized characterization ...

    • On the numerical study of fatigue process in rail heads by means of an isotropic damage based high-cycle fatigue constitutive law 

      Jiménez Reyes, Sergio; Barbu, Lucia Gratiela; Cornejo Velázquez, Alejandro; Oller Martínez, Sergio Horacio (Elsevier, 2022-01)
      Article
      Restricted access - publisher's policy
      The fatigue phenomenon has been historically related to the railway industry. Nowadays, thanks to the high quality of the materials used, most of the recorded problems have been overcome although there are still degradation ...
