abstract="The analysis of accidents involving two-wheeled motorized vehicles reveals the high incidence of fracturing of helmet shells. The severity of injuries increases because of the following two phenomena: the loss of the helmet during the occurrence of collision and the very poor distribution of impact forces against the shock-absorbent material. The occurrence of fractures is closely dependent upon the two following factors: the type of material of the shell and the violence of collisions. The present investigation therefore aims primarily to define a performance criterion in accordance with real-world collisions. This criterion could be required for future certification tests and should enable the selection of the most efficient materials. (Author/TRRL)<p />",
