Estimating the impact force of falling objects
description Drop test is a common testing method in testing the durability of a product. In this report, a drop test simulation will be carried out on an object, in which bottle was chosen as the falling object. The goal is to perform finite element simulations of the drop test and study the impact behavior of the falling object through the simulation. The finite element simulation will be conducted using ANSYS. The bottle was first being modeled using the properties of the bottle that was found available in the market. The bottle was modeled in a way that it was made of a single element. Thin shell element was assigned to the model. Boundary conditions such as initial height and velocity were applied to the model in the simulation study.
