Abstract: Small-scale cantilever beam tests on structurally simulated (seeded) freshwater and saline ice have been performed at the Hamburg Model Basin (HSVA) in order to elucidate the relation between flexural strength, elasticity, salinity and temperature. The tests have shown a considerable increase of the modulus-to-strength ratio if saline ice was warmed up before tested. Furthermore, the results of warm ice tests seem to prove a theory constructed by Weeks and Assur (5) on the relation between flexural strength, elasticity, and brine volume. Based upon the findings of the present investigations, a new ice testing technique was developed and is presently being utilized at HSVA. Besides obtaining a more natural modulus-to-strength ratio, several other similarity conditions are being improved by the new testing technique.
