Conclusion
The finite element model of corrugated plpe with end plate fail under the
applied load due to the poor connection between pipe and plate. At this point,
an angle section (4x4x1l4l ls proposed at the connecting point between pipe
and end plate.
Ïhe proposed method of pipe-plate connection shows stress levels acceptable
for the application without reaching the materials properties limit.
