The behavior of materials under impact loading tests are important in both research and practice, and practical testers are, in a narrow sense, only Charpy and Izod. However in many cases, this data cannot directly lead to the impact strength; the evaluation method for tensile impact property of materials is not always established. In particular, with toughness neither the definition nor the measurement technique has been well-defined.<BR>In this study, a weight-dropping impact-tester is manufactured, with which the relationship between time and load is measured, then the impact-strength is determined from the maximum load. Also, the “Impulsivity” —the ratio between the standard impulse calculated by means of the maximum load and the impulse of the material taking no account of the strain and the reduction— is defined, and based on the relationship between the impact strength and this “Impulsivity”, a method to evaluate the materials’ toughness is proposed.
