Today’s hockey stick blades consist of various foams, geometries, wall thicknesses and curvature patterns across and within manufacturers. The combination of these different characteristics yields great contrasts in the feelings perceived by players. It also translates into different linear and torsional stiffness properties.

The hockey slapshot is an inherently complicated dynamic problem as it involves interactions between the hockey stick, the ice, the puck and the players’ hands.

Such an intricate dynamic event, combined with a complex blade construction, leads to an interesting problem, which can only be simulated to a certain extent using Finite Element Modeling (FEM). A better understanding of the effects of hockey blade construction on the dynamic behavior of the blade during a slapshot would be greatly beneficial.

The objective of this project is the development of a technique allowing the study of blade deformation during a dynamic event, in particular a slapshot. The focus will be put on using Digital Image Correlation (DIC) technique to identify differences in blade behavior based on their specific constructions. This will provide valuable information for further research in blade development as well as define certain blade characteristics to be used as guidelines for customers.
