Ice Screw Analysis Introduction 3D Models Material Properties Analysis Results Discussion Introduction Ice Screws are devices used by ice climbers to anchor the rope to the ice for protection in the event of a fall.  These screws are hollow tubes made of hardened alloy steel with cutting teeth on one end and a hanger which acts as a crank handle on the other.  The tubes are also threaded with a coarse, high profile thread that facilitates insertion and prevents direct pullout.  Much testing has been done in the lab and in the field to determine the holding power and optimum angle of placement for an ice screw.  Their results show that placing a screw perpendicular to the surface of the ice or at a  slightly down angle holds the highest load.  Long falls can generate tremendous forces on these screws so getting ...
