How to include the weight of a model in a static analysisHi everybody,
I' have to simulate (Mechanica structure) a plastic part which is made of a shell of 3 plastic layers.
All the part is a plastic shell (I assume a constant thickness) like kids garden games, dustbins...
The particular point of this project is that the shell is made of 3 differents plastic layers :
inner : Polyurethane
midlle : Polyurethane foam
outer : Polyurethane
So, I don't know how to handle this.
1/ Equivalent material
I thought about make a machanica square model made of 3 layers of plastics and compare with a classical material in sames conditions and adjust the "equivalent classical material" for having sames results than 3 layers model.
2/ Using composite materials idealisation
In this cas that should be more simple than real composite (3 layers of isotrope and homogeneous material), I don't know how to do with ProE.
Any other method ???
Thanks a lot for any advice,
