I've recently had the opportunity to take another look at plasticity in the large deformation context. I've avoided going into geometric and other issues involved with multiplicative deformations (points stressed in earlier blog posts by Giovanni (node/11545), Arash (node/11623) and Xiabo (node/11599). Attached are some old notes that I'd prepared some years ago to help me with the details. I hope they're of use to other students of mechanics.

Call for Submissions
2nd Y.C. FUNG STUDENT PAPER COMPETITION ON BIOMECHANICS, BIOPHYSICS AND BIOMATERIOMICS
EMI 2012 Conference June 17-20, 2012, Notre Dame, IN (http://emipmc12.nd.edu/index.html)
Sponsored by the Biomechanics Committee of the Engineering Mechanics Institute (EMI), American Society of Civil Engineers (ASCE)
In my previous blog, I complained about colleagues developing constitutive models without having any notion about the specific nature of deformation and damage and their micromechanical mechanisms. Unfortunately, this happens more often than one might (or would like to) believe, as a recent example testifies.

Looking at the title and the Abstract:
These positions have been filled.
hey guys please help me,
i need to define my revolution points i.e. the circle by x.y.z. coordinates and i dont know how to do that.
if that is not possible please tell me how can i change the system to cyclindrical coordinates please.
i
have to draw a spring and for that i know the points in cylindrical
system. i cant define in 2d as for less than 90 degree it will not be in
xz or you know like that plane. it will also be helful to define plane
if i can.
Can any one help me in APDL (Ansys) modeling of cylindrical panel for buckling analysis
Hi.
The topic of my thesis is about analysis of RC cooling tower under earthquake loading. The way of this analysis is FEM & for this analysis, I'm doing with "Abaqus" software.
I ask that this software can analysis this structures?
and
for modelling of the rebars of X-legs in this structure, what can I do?
Thanks.
