This is what i did today:
We wanted to be able to represent this metallic porous structure, in a FEM program. So we came up with this procedure:
Incase a sample of the porous material in epoxy resin. Grind it down. Take a microscopy. The image is about 0.5 mm wide.
Then apply a few filters, through CS3, and get the contours of the pores lined out
Then process the saved BMP image, through a converter, to a DXF file.
Import the DXF to SolidWorks, create a 3dmodel from the dxf as a sketch
Export the solid part to Proengineer, and use Mechanica to do FEM calculation:
When the process is streamlined, it will be possible to work out some of the “chain links”.
