Numerical study of impact angle effect in low velocity impact on a plate

In this study, the low-velocity impact of an impactor with a spherical tip on a plate is investigated. In this study, the initial velocity of the impactor in the direction perpendicular to the plate remained constant and only the angle of the impactor is changed. Considering the impactor as a rigid object and the plate as a deformable object, the simulation is carried out in ABAQUS finite element software. In order to validate, the results with zero-degree angle are compared with the theoretical results of other articles. The effect of impactor angle on a series of parameters of the impact responses in the direction perpendicular to the plane are (Y-axis) studied. The results show that with the increase of the impactor angle, the maximum contact force, the maximum von Mises stress at the impact site and the contact time are decreased. By increasing the angle of the impactor, the final velocity of the impactor is changed from positive to zero and finally negative.
