During hot summer days the rubber
in the container flows and produces hydrostatic pressures
on the container walls and base.

The Challenge
Design and test a container that will withstand the expansion and contraction
of rubber undergoing temperature fluctuations during transportation,
knowing that the rubber and the container's plastic will react differently.
The Solution
Perstorp Xytec designed a polyethylene container with nonuniform rib-stiffened
walls, a base with detachable wall bands and one detachable side wall.
Novacomp made a model of the container and modeled the rubber as a cube,
computing the increase in wall loads from the wall's contraction resisted
by the rubber load.
The analysis led Perstorp Xytec to
add more rib stiffeners to the container design to distribute the loads.
Summary and Metrics:
- The finite element analysis verified the increase in the container
wall loads due to a drop in temperature from 120 degrees F to 40 degrees
F.
