The study presents techniques for precise uniaxial testing of ice strength and deformability. The authors performed uniaxial tension and compression tests at constant displacement rate on bubbly polycrystalline ice, analyzed fracture mechanisms, and compared results with prior studies. The tests produced stress–strain curves, elastic moduli, rupture/yield strengths, and failure strains across various strain rates, including data for HF‑doped ice, and the fracture mechanism was compared with previous studies.
Abstract Techniques for making precise uniaxial tests for strength and deformability of ice are described. Results are given for tests made in uniaxial tension and uniaxial compression at constant displacement rate, using bubbly polycrystalline ice. These results include stress/strain curves, elastic moduli, rupture or yield strengths, and failure strains, all for a range of strain-rates. A few results for ice doped with hydrogen fluoride are also given. The fracture mechanism for ice is discussed, and the test results are compared with data reported by previous investigators.
