VOP release

Special release for use in the UGent course Vakoverschrijdend project bouwkunde for the 3rd bachelor Civil Engineering.

Groundhog day 2023

Release of v0.9.0 for Groundhog Day 2023.

The biggest change is the addition of code for axial pile capacity calculations with various skin friction and end bearing methods.

All changes are listed below:

• Added shearwavevelocity_compressionindex_cha for estimate shear wave velocity when stress conditions and packing density are known

• Refactoring of code for element properties in a CalculationGrid object

• Added axial capacity basic code and notebook

• Added hatching to Matplotlib logplots

• Added stress dilatancy theory according to Bolton (1986)

ISFOG2020 in 2022

This release of groundhog is dedicted to all the organisers and contributors to the 4th International Symposium Frontiers in Offshore Geotechnics (ISFOG), taking place in Austin while the new version is released. This conference is a 5-year milestone for the offshore geotechnical community and even though we had to wait for it for a long time, it is going to be a great event. Many offshore geotechnical engineers are really enthousiastic about Python and I hope to include more of their requests and models in upcoming releases.

An important highlight of this release is the change of the license to GNU GPL v3 which allows commercial use as long as the package is credited. I am convinced that groundhog will benefit from use in a commercial environment and I hope to collect feedback and support from practicing geotechnical engineers worldwide.

Another new features is the functionality for settlement and pore pressure dissipation analysis for which two tutorial notebooks are available.

The other changes are listed below:

- Improved margin settings for PSD plots
- Added correlation between acoustic impedance and bulk unit weight from Chen et al (2021)
- Added common-origin approach for liquefaction assessment according to Saye et al (2021)
- Implemented cyclic shear stress ratio equations according to Youd et al (2001)
- Small change for the plotting functionality of Prandtl's failure mechanism

- Added new modules for standards. Started with Eurocode 7-based parameter selection
- Modified Koppejan calculation to use standard 'Depth from [m]' and 'Depth to [m]' columns for the layering
- Added LogPlotMatplotlib for plotting of logs with Matplotlib
- Added functionality for parsing AGS3.1 files using the agsformat argument in the AGSConverter
- Added possibility of plotting friction ratio Rf instead of another panel to plot_raw_pcpt
- Bugfix in Boussinesq stress calculation below a strip footing
- Add general functionality for gridded calculations (``CalculationGrid`` in the ``soilprofile`` module)
- Added 1D excess pore pressure dissipation calculations based on finite difference analysis
- Added class for settlement calculations (``SettlementCalculation``) in the ``shallowfoundations.settlement`` module
- Added module for excavations and started with code for coefficients of active and passive earth pressure
- Changed license to GNU GPLv3
- Added placeholders for constitutive modelling functionality (constitutivemodels module)
- Added tutorials for settlement and consolidation functionality
