We are pleased to release the Autumn 2017 edition of the PLAXIS Bulletin, including two new user articles on PLAXIS 3D and the PLAXIS 2D Thermal with the Frozen/Unfrozen Barcelona Basic Model. We also highlight some upcoming developments and review our recent activities like our PM4Sand roadshow, new additions to the PLAXIS 2D and 3D software, as well as some new Python based tools.
In the New Development column we review the history of our Dynamic module which started in 1998 in PLAXIS 2D and was later extended with PLAXIS 3D Dynamics in 2011. The segment continues to discuss upcoming new calculation possibilities and a new material model, PM4Sand, which should all become available in 2D 2018. Through these developments we ensure that users can rely on PLAXIS to offer state of the art facilities for liquefaction and general dynamics analysis.
In the PLAXIS Expert Services update we discuss constitutive modelling services provided to Tractebel Engineering in order to model compressible elements for tunnel linings in PLAXIS 3D. The work was delivered as a User Defined Soil Model and offered the client a quick, convenient and time-saving solution for their projects.
In the first user contributed article the authors discuss the three-dimensional modelling done as part of the development of three new buildings with basement levels, situated in a triangular site. The site will feature as a large transport hub connecting the eastern parts of Gothenburg. The three-dimensional analysis was necessary due to project requirement calling for a detailed ground movement analysis to confirm the impact of pile driving near the adjacent existing infrastructure.
In the second article the authors investigate the behavior of the Caen’s silt in frost heave through physical experiments. This Caen silt is highly frost susceptible. The authors then performed a back analysis with PLAXIS 2D and the Thermal module, as well as the new Frozen/Unfrozen Barcelona Basic model, in order to prove the merit of using PLAXIS 2D to estimate potential damages due to frost heave.
The Plaxis Americas segment discusses the past activities held in the western hemisphere, like courses, but more importantly, the West Coast seminars on dynamic analysis and PM4Sand. Existing users, but also people unfamiliar with PLAXIS, were invited through several seminars to find out about our user friendly and robust solutions to perform dynamic analysis and were introduced to the more increasingly used PM4Sand model soon to be available in PLAXIS 2D.
In Recent activities, we discuss the new PLAXIS Coupling Tool bringing the structural and geotechnical engineering communities together, the PLAXIS 2D to 3D converter, and the new geotechnical capabilities introduced in the PLAXIS 2D and 3D 2017 releases.
We hope you will enjoy another solid edition of PLAXIS related content and we look forward to receive your feedback on this 41st edition of the PLAXIS Bulletin!
The Plaxis Bulletin is the combined magazine of Plaxis bv and the Plaxis users association (NL). The Bulletin focuses on the use of the finite element method in geotechnical engineering practise and includes articles on the practical application of the PLAXIS programs, case studies and backgrounds on the models implemented in PLAXIS.
