fem on piece in abs got x fdm

[gianni76]

Good morning.
for verification needs of various breaks of some pieces I find myself having to study the behavior of components made with technology "prototypal press" (stratasys printers) in abs material (m30i, absplus, m30i, etc.. )

I believe, but I am not sure and hope someone can help me, to have to consider the material constituent the finished piece as orthotropic (then to hold characteristics of effort and elastic module own of the aps for the direction of "print" while in the perpendicular direction, between the layers, I think it is necessary to detect such characteristics from a traction test.

It's correct, someone's already tried and maybe he's got some results to pass. suggestions on this?

Thank you all. .

It seems correct.
in any case the traction test already that you are advised to do it also in the direction "print".

Okay, I thank you. Of course, I must also study the other direction. if someone had suggestions.. for now I've completed the modeling of the auditions and I'm looking for someone who can do the test. .

Gianni,
I'm telling you
"fem simulating materials other than steel"
where some interesting calculation considerations have emerged certainly also applicable to thermoplastics for your pieces.

Hi.
if you need it again I can do the tests, work in a lab where we have instron dinamometers to do traction, compression, bending etc.
