Dr. Guofang Xu visited ITASCA in April 2015

 

A visco-hypoplastic constitutive model was developed at IGT, BOKU. By simulating some creep tests on single element at different stress levels, this model showed a good ability in describing the viscous behavior of geo-materials. In order to simulate some practical engineering problems, such as the long-term stability of slope and tunnel, the model was planned to implement into FLAC3D. The dynamic link library (.dll) file was created for the implementation and some preliminary results were obtained using the old version of FLAC3D. Owing to the compatibility and syntax variation, the new version of FLAC3D has not been fully used.
