Phone Drop Test
Introduction
Drop tests are commonly performed to evaluate how consumer products respond to impacts and high accelerations. This example uses the Solid Mechanics, Explicit Dynamics interface to numerically simulate a drop test of a mobile phone. The simulation highlights the permanent plastic deformation of the aluminum case and the damage sustained by the glass screen.
Model Definition
Figure 1 shows the setup employed for drop test simulation, which consists of a mobile phone positioned just before impact with the ground.
The phone geometry includes the case, screen, and simplified internal components as shown in Figure 2.
The metal case is modeled as aluminum with an elastoplastic constitutive law incorporating linear isotropic hardening. The screen is modeled as glass, with a damage model to simulate the brittle behavior. The internal components are represented by linear elastic materials.
Contact interactions are defined both between the phone and the ground, and between the internal components and the case.
The phone is given an initial velocity of 6 m/s in the vertical direction, corresponding to a drop height of approximately 1.83 m. The ground is assumed to be perfectly rigid.
Because of the short duration of the event and the nonlinearities introduced by contact interactions and material models, an explicit time integration scheme is employed for computational efficiency.

Figure 2: View on the internal components.
Results and Discussion
Figure 3 shows the permanent strain that is developed at the corner where the phone impacts the ground, whereas Figure 4 shows the crack width on the glass screen at the last computed time in the simulation.
Figure 5 shows the evolution in time of various energy quantities. Initially, the total kinetic energy (blue in the graph) quickly reduces due to the high deceleration during the impact with the ground. At the same time, part of this energy is dissipated as irrecoverable plastic deformation while the remaining part is stored as strain energy (green). As time progresses, the vibrations induced by the impact are witnessed in the plot by an exchange between kinetic and strain energy, while the dissipated energy (red) steadily increases due to crack propagation and artificial viscosity.
The graph also allows you to monitor the stabilization energy and the artificial kinetic energy, which remain low with respect to the physical ones throughout the simulation. The total contact energy shows a peak in correspondence with the impact between the phone and the ground.

Notes About the COMSOL Implementation
•
The Solid Mechanics, Explicit Dynamics interface along with the Explicit Dynamics study step automatically sets up explicit time stepping and provides automatic evaluation of the stable time step.
•
An Interior Contact node is added to model the contact between the screen and its support.
•
An Artificial Viscosity node is added to partially damp out the energy of the impact.
•
A Mass scaling node is added to inject localized artificial density where small elements would otherwise limit the stable time step.
•
Attachments between the internal components and the case are modeled by a Continuity condition. This allows nonconforming meshes at each interface, which in turn makes it easier to be better control of the mesh size and quality of each component.
