  • In: Computer methods and advances in geomechanics. - Rotterdam : Balkema Publishers, A.A. / Taylor & Francis The Netherlands. - 9061911893 ; , s. 569-574
  • Conference paper (peer-reviewed)abstract
    • Optimization-based methods for the determination of constitutive parameters of material models are evaluated. Rosenbrock's and Levenberg-Marquardt's algorithms are considered in particular. Based on experimental data for Swedish silt, two plasticity models are calibrated and their performances are compared

  • Characteristics of constitutive relations in soil plasticity for undrained behavior
  • 1992
  • In: International Journal of Solids and Structures. - : Elsevier BV. - 0020-7683 .- 1879-2146. ; 29:3, s. 363-380
  • Journal article (peer-reviewed)abstract
    • Elastic-plastic relations which are subjected to the constraint of incompressibilily, that is pertinent to undruined behavior of soils, are assessed and compared with the relations for drained behavior. The tangent relations for mixed control variables (total stress and strain components) are established explicitly. The criterion signalling plastic loading, and elastic unloading, is considered in particular. A criterion for unique response, as expressed in terms of elastic and plastic loading, is formulated as a condition on the particular plastic modulus that corresponds to undrained behavior. Stability is discussed in terms of appropriate critical values of the plastic modulus. It appears that, for a frictional material, dilatancy has a stabilizing effect whereas contractancy may be destabilizing compared to drained behavior.
