Abstract

The tensile strength of rocks can be obtained various methods and the bending tests are also used for such a purpose. However, there was almost no study on the bending tests under impact loads when the authors initiated this study. The authors developed a special jig and it was used for bending tests under both impact loads and static loads and it is also possible to apply axial loads on rock beams. The authors compare the experimental results on several rocks subjected to impact and static loads. Furthermore, some discussions are given on the tensile strength of rocks determined from three-point bending and Brazilian tests under both impact and static loads. The authors discuss the experimental results and discuss the effect of the impact velocity and momentum on dynamic bending strength characteristics of rocks in this study.
