      Ultrasonic and bender element tests in the laboratory are typically used to measure elastic modulus and damping ratio. However, interpretation of the results is challenging for a variety of reasons, including the influence ...
    • Simplifying calibration of bonded elasto-plastic models 

      Rios, Sara; Ciantia, Matteo Oryem; Gonzalez, Nubia Aurora; Arroyo Alvarez de Toledo, Marcos; Viana da Fonseca, A. (2016-03)
      Open Access
      Using realistic constitutive models for artificially cemented soils is advantageous in design. However, the price of that increased realism is often a more elaborate model, which is difficult to calibrate. A database of ...
