v2.5.2

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()

v2.5.0

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.
