A test method is developed for evaluating the Impact Endurance Limit of a material. The Impact Endurance Limit is defined as the energy per blow in tensile impact loading below which the specimen will withstand an indefinitely large number of blows without rupture and this value is given for ALCOA 24ST and 14ST, with and across the grain, and Dowmetals X and Z-l with the grain. Evidence is presented that this value probably does not depend directly either on the energy absorbed in breaking in one blow or on the brittleness of the material.
