  • Aceleración de deslizamientos por efectos térmicos: modelación mediante el método del punto material 

    Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2017)
    Conference report
    Open Access
    La ocurrencia de deslizamientos rápidos se ha ligado a la pérdida de resistencia efectiva a lo largo de la superficie de rotura debido a excesos de presión de agua inducidos por el calor generado durante el propio movimiento. ...
  • Efectos del cambio de la velocidad de deformación sobre la resistencia del suelo: aplicación del método del punto material 

    Alvarado Bueno, Mauricio (Universitat Politècnica de Catalunya, 2013-12-13)
    Master thesis
    Open Access
    La velocidad de deformación afecta las propiedades mecánica de un suelo tanto en su estado inalterado (propiedades pico) como en estado residual. Este efecto conocido como “Rate effects”, ha sido estudiado en laboratorio ...
  • Effect of shear band thickness on the termo-hydromechanical coupled analysis of landslides 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Alonso Pérez de Agreda, Eduardo (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Conference report
    Open Access
    Thermal effects induced by the own motion of an unstable mass have been included in the analysis of the post-failure behavior in early works, most of them with the aim of looking for the causes of the rapid acceleration ...
  • Landslide motion assessment including thermal interaction : an MPM approach 

    Alvarado Bueno, Mauricio (Universitat Politècnica de Catalunya, 2018-04-23)
    Doctoral thesis
    Open Access
    Risk associated with landslides of natural or man-made origin depends on the prediction of the post-failure behaviour of the mobilized mass. Numerical models capable of integrating the landslide geometry and its evolution, ...
  • Novel analysis for large strains based on particle image velocimetry 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio (2017-07)
    Article
    Open Access
    Over the last few decades, the particle image velocimetry (PIV) technique has become an interesting tool used to measure displacements in the field of experimental mechanics. This paper presents a procedure to interpret ...
  • Novel procedure to validate MPM results by means of PIV measurements 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Parera Morales, Ferran; Yerro Colom, Alba (2017-02)
    Article
    Open Access
    The Particle Image Velocimetry is a powerful non-invasive technique to analyse displacements in experimental tests. Displacement increments elapsed between the capture of two digital images are commonly measured on points ...
  • Nuevo método para la interpretación de imágenes digitales de inestabilidad mediante la técnica PIV. 

    Alvarado Bueno, Mauricio; Ruiz, Álvaro; Pinyol Puigmartí, Núria Mercè (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Conference report
    Open Access
    Este artículo presenta una metodología que proporciona los desplazamientos acumulados, velocidad, aceleración y deformación de puntos asociados a partículas reales a partir de las medidas obtenidas mediante la técnica ...
  • Thermal effects in landslide mobility 

    Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Alonso Pérez de Agreda, Eduardo; Zabala, Francisco (Thomas Telford, 2018-06)
    Article
    Restricted access - publisher's policy
    The paper describes a thermo-hydro-mechanical formulation to model thermal-induced effects due to the irreversible work input generated during the soil deformation. The model was implemented into a Material Point calculation ...
  • Wetting collapse and failure of and slope tested in centrifuge machine 

    Pinyol Puigmartí, Núria Mercè; Ruiz, Álvaro; Alvarado Bueno, Mauricio; Caicedo, Bernardo (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Conference report
    Open Access
    This paper presents a centrifuge model of a silty clay slope. The increase of the gravity accel-eration is applied to the slope under unsaturated conditions. The slope is wetted in flight by means of water injection from ...
