Steel selection for Arctic ships: effects of elevated loading rate on toughness

AbstractSteel selection standards embodied in the Canadian Arctic Shipping Pollution Prevention Regulations (CASPPR) are reviewed with special regard to the strain rates expected to be encountered in service. Recent work on the effect of strain rate on toughness of ship plate is presented, and its implications for the adequacy of the revised CASPPR are discussed. Resume On examine les normes relatives a la selection des aciers incluses dans les reglements sur la prevention de la pollution des eaux arctiques par les navires en portant une attention particuliere aux vitesses de deformation prevues en service. On traite des travaux recents re1atifs a l’effet de la vitesse de deformation sur la tenacite des toles pour navires ainsi que de ses repercussions sur la pertinence de la version revisee du reglements.
