Dataset: Mixed-mode I/III fracture of anticracks in porous weak layers

Experimental dataset for: Mixed-mode I/III fracture of anticracks in porous weak layers This dataset contains the experimental results from Mode III mixed-mode weak layer fracture tests (M3-WLFT) conducted at the Steintäli in Davos, Switzerland. Files: M3DC_raw.parquet — Master data for all experiments (one row per test, identified by automated file number (AFN)) M3DC_raw_info.parquet — Column metadata: abbreviation, units, data type, long name, description The master data contain experimental metadata, sample geometry and snow properties, loading data (load–displacement records and manual annotations where applicable), derived Mode I and Mode III energy release rates, and mixed-mode interaction fit parameters. The data can be loaded with Python using pandas.read_parquet(). The full analysis notebook (M3DC_Notebook.ipynb) is provided in the accompanying code repository on GitHub. Contact: [e-mail]
