Abstract: Boundary conditions play an important role in the formation and orientation of shear faults. The paper investigates their influence upon the formation and orientation of terminal shear faults in S2 columnar ice under biaxial compression. Three end conditions were used: brass, sand-paper and latex. It was found that the average inclination angle of the shear fault, measured with respect to the vertical axis, increases with the increase in the specific degree of confinement characteristic of each type of boundary condition. The effect is explained in telms of the influence of boundary conditions on the principal stress directions.
