- According to earlier studies of brash ice covered channels and problems connected with winter navigation laboratory tests have been performed, treating brash ice as a Mohr-Coulomb material cohesion and shear properties have been studied. A shear box, 0. 5 multiplied by 0. 5 m, equipped with a water bag for normal loading, was used. The force required to shear the rubble was determined as a function of normal force, shear rate and ice piece thickness. The test results are analyzed and presented. The results are also compared with results from other studies and the applicability is discussed
