title = "Finite element analysis on capsule end faces of the impact toughness tester",
abstract = "Toughness index is an important parameter of the quality of super-abrasive grits. In order to improve the design of the toughness index tester more reasonably and efficiently, we calculated the velocity of a steel ball in the capsule and simulated the impact process between the steel ball and the different capsule end faces with the ANSYS/LS-DYNA. The main results are as follows: (I) the maximum velocity of the ball is approximately 2.0106m/s. (II) with the increase of the curvature, the maximum value of normal stress declines while the effective area rises. (III) the maximum shear stress cannot cause diamond grits to break directly, but it can make small cracks and defects of the impacted grits propagate. These assertions are validated by the simulation which explains the experimental phenomenon well.",
