TEARING RESISTANCE OF ADVANCED DOUBLE HULLS

This paper studies the cutting by a wedge of advanced double hull (ADH ) small-scale models. A total of six cutting experiments were performe d with six different wedge geometries. Complex deformation patterns ob served in the damaged specimens were simplified to obtain a closed-for m upper bound for the steady-state cutting force. The ADH steady-state cutting force solution varied from 6% above to 12% below the experime ntal mean steady-state force. The absolute average error is 5%.
