In designing machine parts or structures which must withstand an impulsive load, it is fundamentally important to know the dynamic deformation of the material at its contact part and the impulsive force generated at that part. In this paper, a new method has been proposed for measuring the impulsive force generated at the contact part in collision. This method is effective for direct measurement of the impulsive force with relatively high sensitivity for normal impact. By means of this method, an impact test on commercial pure aluminum bars with different lengths and spherical ends is performed. From the experimental results, it is found that the generated force and the volume of the deformed part at the contact end increase in proportion to the impact velocity, and that the generated mean stress on the contact part is constant and independent of the radius of curvature of the spherical end and the impact velocity.
