LAYERED SLABS ON COMPLIANT WEAK LAYERS

WEAC v2.5 provides Python 🐍 implementations of closed-form analytical models for the mechanical analysis of **stratified snow covers** on compliant weak layers.

FEATURES

- Adds the computation of the cut length where the slab comes into full contact (more than a singular point) with the base layer in a propagation saw test to `weac.tools.touchdown_distance()`

LAYERED SLABS ON COMPLIANT WEAK LAYERS

WEAC v2.5 provides Python 🐍 implementations of closed-form analytical models for the mechanical analysis of **stratified snow covers** on compliant weak layers.

FEATURES

- Analyze slab touchdown 🏈 after weak-layer collapse in propagation saw tests (PSTs) by setting `touchdown=True` at model setup
- Use `weac.tools.touchdown_distance()` to calculate the PST cut length at initial contact between slab and base layer after weak-layer collapse and the steady-state touchdown distance during unstable crack propagation.

BUG FIXES

- Fixed Zenodo indexing

FEATURES

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