Analysis of scale effect in ice flexural strength
Ice flexural strength is an important parameter in the assessment of ice loads on the hulls of ice-class ships, sloped offshore structures, or sloped bridge piers. While scale effects in compressive ice strength are well known, scale effects in ice flexural strength are not proven. To investigate sc...
