This animation shows a cross-sectional view of
a cell phone antenna when dropped from 1.5 meters. DRD performed this
dynamic analysis to determined the behavior of the antenna when it falls
from a person's belt or hand. The weight of the entire phone was simulated
but only the cross sectional view of the antenna portion is shown for this
animation.
Nonlinear contact is modeled with friction
between the floor and the hyperelastic cover and between the cover and the
internal plastic frame. Bonded contact is used to hole the frame and
retaining ring together.
Before impact occurs, stress contours can
be identified in the frame from the initial interference of parts during
assembly.
Plasticity is modeled in the frame and a
permanent deformation in this plastic part can be identified as the
antenna bounces off the ground.
