Modification of a motorcycle helmet has been performed by inserting an electronic device in the helmet's inner liner. Therefore, a hole requires to be made to place the device. This study aims to analyze the impact loading performance of a motorcycle helmet due to an impact from the top, rear, and side. The investigation of stress distribution and acceleration experienced by the helmet is analyzed by utilizing finite element method simulation. The results indicate that the hole position is not in the impact area. The outer shell experiences higher stress than the inner liner in all testing conditions. The rear impact causes the highest value of the outer shell stress, where for the inner liner, the side impact contributes to the maximum value of the stress. Headform linear acceleration reaches the peak than is higher than the basic requirements of the helmet testing standard. © 2020 Institute of Physics Publishing. All rights reserved.
