AbstractCantilever beam tests carried out on a freshwater ice cover showed that introducing stress relief holes at the root of the beam increased flexural strength, as determined from simple beam theory, by to , compared to conventional cantilever beams. Finite element analysis confirmed the existence of stress concentrations at the edge of the beam, 1.5 times the centre stress for the case of a stress relief hole and 2 times in the case of a cantilever beam without stress relief holes. A correction factor of 1.08 has been determined for the flexural strength of cantilever beams with stress relief holes at the root; for those with no special root treatment, the correction factor is 1.35.
