In physical modelling, size or scale effects may exist due to the incomplete replication of the relevant details of the prototype. A size effect in ice flexural strenght is evident for experiments and has also been illustrated theoretically. When modelling ice/structure interaction at reduced scale, the possible influences of the mmdel size should be addressed. This paper presents experimental evidence of a size effect in the flexural strength based on measurements on small freshwater and saline ice beams conducted at C-CORE and the Institute for Marine Dynamics (IMD). The implication of this size effect on physical modelling is discussed, and a few remedies are suggested. Peer reviewed: Yes NRC publication: Yes
