abstract="A mathematical model of a sideboard collision in ice hockey has been developed and was used to compare the design characteristics of ice hockey helmets.  The results indicate that, for an initial impact velocity of 11 feet (3.35 m) per second, the helmet liner thickness and the maximum linear acceleration imparted to the head appeared to be within satisfactory limits.  Any helmet built only do these specifications would be expected to fail, however, if subjected to impact on the order of 20 feet (6.1 m) per second.  It is suggested that improvements in the quality of a hockey helmets can be made by raising the criterion impact for protective standards closer to a value of 20 fps.<p />",
