This study analyzed the deformation and displacement of balls and duralumin bats during and after batting balls usinga finite element method. In the analysis, the balls were collided against the bats fixed at their grips with the velocityof 5.79×104mm/s. The results are as follows. 1. After about 0.5ms from the time the ball was in contact with the bat,the cross-section of the bats and the balls flattened most. 2. The balls left the bat in about 1.2ms after collision, atwhich, the cross-sections of the bats and the balls nearly returned to their original forms. 3. Bats continued bendingeven after a ball is away from the bat.
