Simulating Deformation of Plastic

Simulating Deformation of Plastic

Simulating Deformation of Plastic

(OP)
I have a plastic cover that is not designed to be stacked, but it has been required to determine how many of these covers can be stacked.  I'm looking for suggestions on how I can possibly deform these shelled part models to simulate the expansion and compression of these parts when stacked.

I cannot redesign the parts, as the $50k mold is are already in process.  This is a bean-counter exercise to determine how many covers can fit on a standard pallet.

I forgot, I'm on SW05 SP4.0.  I don't have the neat-o new features.

The only way I know of is through COSMOSWorks. I don't know if COSMOSExpress will work.

RE: Simulating Deformation of Plastic

COSMOS (full version, not Express) can deal with multiple parts.  Express does only one part at a time.

However, if you learn the difference between a Force and a Pressure, you can probably simulate the plastic flexure as needed.  It's a hack, and it will only give you as good an output as you give it input.

I'll remember this for the future.  The problem was not presented well to me.  I was told we must "stack covers" to fit them on a pallet to ship to EU.  In reality, the question being asked was how many covers can we fit on a pallet.  Since this opened more doors (stacking not a requirement), I was able to lay the covers flat, nest them together, and was able to fit 4X as many covers in 1/2 the space.

I love well defined problems.
