抄録

This paper is concerned with a new measuring method for the impact tensile strength of concretes. The method of impact tensile testing is based on the propagation and concentration of both tensile stress waves reflected from the ends of a specimen and a striking bar. The impact tensile tests of concrete are performed by making use of the Hopkinson-bar technique. The impact tensile strength and fracture behavior of concretes are discussed by the simple theory of stress wave propagation in a bar. The statistical analysis of the experimental data obtained in a series of the impact tensile strength test is presented and compared with that of the static tensile and bending tests of concretes. The impact tensile strength of the concrete is significantly influenced by loading rate, and it is found to be approximately twice the static value.
