Tension cracking events in permafrost modelled by beam bending tests at < 0 °C Fracture mechanics in frozen soil investigated through novel instrumentation Differentiating between sudden loss of strength and nucleation of micro cracks Transitions between ductile/brittle responses identified for volumetric ice content wi, strain rates and temperature T
