Characteristics of pebble shape and the amount of pebble abrasion measured with a replica reproduced on a curling rink.

The shape of pebbles on a curling rink was measured using a replica of the ice surface of the rink to understand the characteristics of pebbles after being in contact with stones. We focused on pebbles with flat tops for which the average shape was 3.81 mm in diameter at the lower base, 1.

The importance of the surface roughness and running band area on the bottom of a stone for the curling phenomenon.

Curling is a sport in which players deliver a cylindrical granite stone on an ice sheet in a curling hall toward a circular target located 28.35 m away. The stone gradually moves laterally, or curls, as it slides on ice.
