Stress-induced martenstic phase transformation in Cu-Zr nanowires
Hi Friends
I want to share some of our recent research work on the stress induced phase transformation of CuZr nanowire which is published in Materials Letters.

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
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.

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.
Bending and 2D Elasticity: Going Back in Time
The following is a (relatively minor) question which had occurred to me more than two decades ago. By now I have forgotten precisely when it was... It could have been when I was in my TE (third year engineering) at COEP. ... Or, perhaps, it was later on, when I as at IIT Madras (studying stress analysis on my own). ... I don't remember precisely when it occurred to me, only *how* it did---it was when I was poring over the first part of Dieter's book.
Bergstroem Boyce Model - inelastic part
Hi,
I was wondering if anyone has experience in implementing the Bergstroem-Boyce Model (Constitutive modeling of the time-dependent and cyclic loading of elastimers and application to soft biological tissue, 2001)? I am struggling with the implementation of the viscoplastic part (Network B) of the model:
