Bone Remodeling Subroutine
Thu, 2015-05-21 18:20 - Braad
Dear all,
I am a PhD student working on mandibular fixations using some smart materials. At this step I am going to work on simulation of bone remodeling in mandible. I am very new to ABAQUS, however after searching the web, I got the key is using in UMAT coding for this problem (???). I have the model and also all the equations ready, I'm going to use Stanford theory for bone remodeling which obtain the stimulus from the strains and the stresses. I have never written a UMAT code, and all the existing samples are complicated and completely irrelevant to may case. Does anyone have a bone remodeling UMAT sample? I really need help!!!
Thanks,

Bone Remodeling
Hello,
yes, you need UMAT.
For a start in UMAT coding get the file
http://imechanica.org/files/Writing User Subroutines with ABAQUS.pdf
it may show up as
http://imechanica.org/files/Writing%20User%20Subroutines%20with%20ABAQUS...
But it will not be of much help to you.
For remodeling see

Bone remodeling codes
Search the web for a code for the model you intend to use. Alternatively, ask the authors of that model if they are willing to share a code, not necessarily for ABAQUS. Your work should help them spread the word, so they should have a keen interest in disseminating a numerics code.
If you refer with "smart materials" to shape memory materials then look up my posting on
http://imechanica.org/node/7001
Regrettably, that custhelp site of Simulia is down. Contact me directly if you need the information I refer to in this posting.
The other option is UMAT coding of shape memory materials.
Good luck
Frank
Thank you very much Frank.
