ANSYS - Coordinate system following a tangent of a curve
Hello everyone,
I'm trying to analyze a composite shell of a light aircraft fuselage. There are some layers - UD reinforcements in the shell of fuselage, that should follow certain path on the shell. So the layer coordinate system should rotate with the tangent of path - 3D curve. I saw a picture in a science paper, where micromechanics of a fabric lamina was analyzed in ANSYS. The coordinate system was following a centerline of a fiber.
Can anyone give me an advice how to do this? Thank you in advance.

Principle of virtual work in case of a large plastic deformation
Hi, all
I have a question about FE formulation for a finite plastic deformation.
I'm a new on the ABAQUS, but how the ABAQUS deals with the plastic deformation
to solve the FE eqation? I think the software use the principle of virtual work and
I'm wondering how the software modify the virtual work term to take the plastic deformation into account (because of dissipation energy)
(Obviously, the formulation must be different with elastic model)
I appreciate your reply.
Continuity in the Plastic Strain Rate and its Influence on Texture Evolution
Classical plasticity models evolve state variables in a spatially independent manner through (local) ordinary differen-
tial equations, such as in the update of the rotation field in crystal plasticity. A continuity condition is derived for the
lattice rotation field from a conservation law for Burgers vector content—a consequence of an averaged field theory
of dislocation mechanics. This results in a nonlocal evolution equation for the lattice rotation field. The continuity
Estimate of Burst Strength of Dents in Pipe
Hi all,
I am a master student doing an analysis to estimate the burst strength of dented pipes, I have been able to model the indenter and pipe. I did a non-linear analysis to create the dent but my problem is how to remove the indenter and apply pressure to come about the burst. please how do I achieve this kind of analysis. I would be very grateful to contributors and examples that would help me solve the problem. The model is being done using ANSYS 11.0

My Eprint papers
Hi,
These are my Eprint papers. Some have already been published as Journal papers, some have not.
I will discuss some of them here someday.
You can link to http://arxiv.org/ and search my name Pi-Gang Luan in Physics [arxive: All], and these papers would be shown to you. There is an exception, my YBE paper ([Colored solutions of Yang-Baxter equation from representations of U_{q}gl(2)] ). In that case you should type [Pi-Gang Luan] instead of Pi-Gang Luan to find the paper.
My Chinese blogs and My Photonic Crystal Book
Hello,
If you can read Chinese, you can visit my Chinese Blogs as follows.

Besides, I and my colleague (Prof. chen) published a Photonic Crystal book: "Photonic Crystals -- From butterfly wings to nanophotonics" in 2005.
Notes on Implicit Update for Bergstrom-Boyce Network B
This post is in response to the imechanica request
node/5034
(a separate post, as I have to attach notes - it would be really nice to be able to attach documents to imechanica comments)
Attached are hand-written notes I have used to implement the Network B for the Bergstrom-Boyce model. They were written for my use only, so if it seems stream-of-consciousness at times, don't blame me. The details should all be there, though.
This is my first 2009 article
Now I come here again.
From now on I want to share with you my research experiences and personal opinion on time dependent quantum system, photonic/sonic crystals, and metamaterials. I would also like to write some articles on science teaching stuff.
I come from Taiwan. Usually I speak chinese, and have no many oppernituties to practice my English, so I wish someone can help me to improve my English. Thanks !
Numerical Evaluation of Crack Tip Opening Displacement (CTOD)
Hai All,
I want to know how to evaluate CTOD form the finite element nodal
values(displacements) that are obtained from the commercial software
ABAQUS.
I am using Elastic-Plastic model for the analysis. Can anybody help me in this regard.
thanking you in advance,
Regards,
