In this study, a drop test analysis of a cell phone was conducted by SolidWorks simulation software. The main purpose is to determine the stress due to impact and produce animation of the cell phone when it falls and hits the ground. First, Five parts, front camera, outer shell, glass screen, home button, and back camera of an i-Phone, were created in SolidWorks according to specific dimensions as part documents and then assembled to develop the model for the study. The materials selected for the phone shell and home button was 7079 AL-alloy, and for the other three parts was glass. The simulation parameters were: drop height – 6 feet, gravitational acceleration – 9.81 m/s2, friction coefficient – 0, and solution time after impact – 25 microsecond. Simulations were conducted for three impact angles of the cell phone, 900, 00, and 450 with the ground at the time of impact. Results show that for impact angle 900, the maximum stress is developed on the lower end of the phone. The stress is uniformly distributed over the phone for an impact angle of 00. Results were not conclusive enough for the inclined angle of impact, so more studies are needed to be conducted to investigate the effect of impact. Future studies are also recommended for different drop heights, different part materials, and floor with friction.
