Hi all
I am modeling a complex muscle with fibre reinforced. The fibre direction is not constant in this muscle. It is changing with the integration point in the model. Is there anyone who got idea on how to simulate the variable fibre directions in Abaqus? Can user subroutine ORIENT do this?
Many thanks,

This may be interesting news for many of imechanicians. (according to pervious discussions)
From GOOGLE Blog:
Remember when I spoke of the Easterlin paradox (a key concept in happiness economics postulated by Richard Easterlin in the 1974 paper "Does Economic Growth Improve the Human Lot? Some Empirical Evidence."[1]
It finds that, contrary to expectation, happiness at a national level
i have an optimization program for structural problem in Matlab software. i found design variables from Matlab. i want to interface this program in to ansys softare to find optimum stress and strain. how can i interface matlab program in to ansys. if any sample tutorilas please send me.
Triangular elements with 2 coincident but untied nodes produce a 1/r variation of stress/strain field.
But the stress/strain field has a 1/√r singularity.
Can you tell me why or recommend me some papers taking about it.
hi
I constructed a head model, which includes muscle, soft tissue, skin and bone. I wrote user material subroutine (umat) for muscle and soft tissue, seperately. I am going to define the muscle and soft tissues properties by using my umats. However, I dont know how to define two user material subroutines (umat) in one model. The subroutines share the same name: subroutine umat(...). If I assign two umats, ABAQUS will be confused, wont know which subroutine to go. Is there anybody who knows how to sort this out?
Many thanks,
ben
Making the Right Moves: A Practical Guide to Scientific
Management for Postdocs and New Faculty
Based on courses held in 2002 and 2005 by the Burroughs Wellcome Fund and
HHMI, this book is a collection of practical advice and experiences from
seasoned biomedical investigators. The second edition contains three new
chapters on laboratory leadership, project management, and teaching and course
design.
A postdoctoral research position is available immediately in the Johnson research group at the University of Illinois at Urbana-Champaign. The position will involve continuum finite element modeling of multiphysics and interfacial phenomena in micro- and nanoscale electronic materials processing applications.
