摘要：
The data of Dunn and Martin (1978), Is reanalyzed using a rigorous application of Hertzian theory to the, impact process. The Young's modulus of steel, required to fit their data to the theory is a factor of about 10(3), too low compared to the values quoted for steels. Thus, doubt is thrown on the validity of their experimental technique, and it is possible that their values for maximum impact force and stress are far too low.
