LAYERED SLABS ON COMPLIANT WEAK LAYERS

WEAC v2.4 provides Python 🐍 implementations of closed-form analytical models for the mechanical analysis of **stratified snow covers** on compliant weak layers.

BUG FIXES

- Fixed data format of energy release rates
- Added switch for touchdown computations

FEATURES

- Choose between slope-normal or vertical PST boundary conditions (`'-pst'`, `'pst-'` or `'-vpst'`, `'vpst-'`, respectively)

**Full Changelog**: https://github.com/2phi/weac/commits/v2.3.0

- Fixed a bug where end coordinates could mistakenly be identified as unsupported when they were actually supported
- Fixed a bug where edge cracks could mistakenly be identified as center cracks

FEATURES

- Sign of inclination `phi` consistent with the coordinate system (positive counterclockwise)
- Dimension arguments to field-quantity methods added
- Improved aspect ratio of profile views and contour plots
- Improved plot labels
- Convenience methods for the export of weak-layer stresses and slab deformations
- Wrapper for (re)calculation of the fundamental system
- Now allows for distributed surface loads
