Need help for running UMAT of Dr. Huang's single crystal

Submitted by Soud Choudhury on

Hello Everyone,

I am a new member of imechanica. I have started to learn UMAT of Abaqus to model my material behavior ( Cu6Sn5, HCP) using crystal plasticity finite element model. I found Dr. Huang's single crystal UMAT to start learning UMAT and I thought that it would be a great guide to start though it is written for FCC mat. But unfortunately I was not able to run the UMAT with it's input file.

link 8, introduced tensile curve and compression curve

Submitted by toni on

Hi.

I'm working  with the element link8 (Ansys 12.1) and I have to
introduced the tensile curve and compression curve, but I don't know,
How I have to introduced its???

 

I have worked with the comands: TB: aniso, miso,..., I think the best
option is: TB, user, but How I have to introduced the values of tensile
and compression curve?, when this are different.

 File attachment is the tensile and compression curve to introduce

Thank you, Toni

Finit element Analysis of mandible bone with implant

Submitted by king_man on

Hi everyone

i work on a bio mechanic project. i am going to simulate a mandible bone
with implant. at first i want to use Materialise Mimics V10 to convert Ct Scan
data of a mandible without implant to a 3D model. i thought i could edit
the exported file on the other software (Ansys or Abaqus) to add the
implant. but, exported file from mimics can not have any edit .Actually
it has not volume and i need to have a 3D solid model. please help me !
