Hello every 1

I must model porous materials in abaqus!!but really i am confused how to create these complex shapes p

voids in my models are not arranged but i thinks that i have to model them regular,how ever i need to simulate an configure like bone structure(specially that some wheres in model have more voids or less some thing like bone)

by the way my models are 3D and thickness of trabeculae|(pores wall) in configure is not constant(just like bone!!)

thanks to all:)

You did not ask any question...

It sounds like you need to create a micromechanical model.

Dear Jorgen actually I am trying to model a porous material not specially micro in scale!!
surely I CAN design some unit cells and copy them to create my model,but is there any other way to simulate very complex models by abaqus?

Thanks

I am still not sure I understand your question. A porous material typically has a complicated microstructure (which does not have to be small in absolute terms), and will require a carefully created Representative Volume Element. You can also use repeated boundary conditions.

I have never seen micromechanical models in which bone or cartilage has been modeled as a poroelastic medium.
