Keywords: finite element, parallelisation, partially and fully saturated soils.

Summary

In this paper the modification of a constitutive model for partially saturated soils is presented, which is formulated in terms of the generalized effective stress and matric suction. The latter model is improved in several respects aiming at an enhanced robustness at the transition from unsaturated to saturated states and at an extension of the range of application from sands to low and medium plasticity clays. The model is developed and implemented such that it can fully utilise the parallelisation features available in the open source finite element program OpenSees, and a number of tests are conducted on the Linux cluster system LEO III available at the University of Innsbruck.
