The numerical modeling of swelling strain and swelling pressure of expansive soils when saturated with a unique set of material parameters is still a challenge that persists to this day. In collaboration with BTU Cottbus and Ruhr University Bochum, we have developed a new hypoplastic model for expansive soils. In our latest publication in the journal Bautechnik, we validate this model by back-calculating numerous laboratory tests and introduce a simplified calibration procedure.
Together with Dirk Wegener from GEPRO Ingenieurgesellschaft mbH (Dresden), we present an extension of conventional analytical settlement analyses that takes into account the accumulation of deformations due to cyclic loads with high frequencies, as they occur for example for machine foundations or railway tracks.
We have once again released a new numgeo version, with many new features, a new html documentation, a "portable" numgeo version without additional software requirements and new examples.
The first numgeo workshop took place on the 24th and 25th of January at the Institute of Geotechnics at TU Dresden. The focus was on the introduction to the various possibilities of the FE software Read more…
