Brinkgreve, R.B.J. (author), Tschuchnigg, F. (author), Laera, A. (author), Brasile, S. (author)Following up on previous research on Automated Parameter Determination (APD), in which the soil stratification and numerical model parameters are automatically derived from individual CPTs, this article describes ongoing research in which the geotechnical modelling workflow is further automated in a BIM / Digital Twin environment. Especially in...conference paper 2023

Laera, A. (author), Vilhar, G. (author), Brasile, S. (author), Brinkgreve, R.B.J. (author)To simulate the behaviour of saturated sands under cyclic loading, the PM4Sand constitutive model (version 3.1) formulated by Boulanger & Ziotopoulou [1], is used. The model can realistically reproduce the pore pressure build-up, accumulation of strain as well as triggering of liquefaction. The effect of dif-ferent relative densities on...poster 2019

Marinelli, F (author), Zalamea, N. (author), Vilhar, Gregor (author), Brasile, S. (author), Cammarata, G. (author), Brinkgreve, R.B.J. (author)Hoek & Brown (HB) failure criteria have been employed over the past decades in common engineering applications due to their extended capability to capture the non-linear yielding of different types of rocks. Often implemented within a perfect plastic framework, this constitutive approach is here enhanced by introducing a softening rule to...conference paper 2019

Laera, A. (author), Vilhar, G. (author), Brasile, S. (author), Brinkgreve, R.B.J. (author)When saturated soils are subjected to an earthquake, the excess pore pressuresincrease, and, in the case of sands, this may cause liquefaction. To simulate the behaviour of saturated sands under cyclic loading, the PM4Sand constitutive model (version 3.1) formulated by Boulanger & Ziotopoulou (2017), is used. The PM4Sand model represents an...conference paper 2019
