Continuity of traction vector
I am looking for a source which has a good explanation of the pill box argument to prove continuity of the traction vector. If you know of such a source (url, book etc) please let me know.
Thanks,

Residual Stress Calculation with Abaqus

Hello There,
Indentation Stress and Displacement Fields
I am looking for stress and displacement fields for indentation of an elastic half-space with a rigid spherical indenter. Anthony C. Fischer-Cripps provides closed form expressions (no derivations) for stress fields in his textbook "Introduction to Contact Mechanics" (Chapter 5, Page 88-89). He cites the work of M.T. Huber[1] which is in German (Annalen der Physik, 1904).
Can someone point me to an English language reference for the analytical derivation of displacement and stress fields in the interior of the specimen ?
Writing User Subroutines with ABAQUS
Dear All,
I think that many students are looking for some tutorials about writing a UMAT in ABAQUS.
You can find a comprehensive tutorial for elastic problems.
This file contains:
• Motivation
• Steps Required in Writing a UMAT or VUMAT
• UMAT Interface
• Examples
Example 1: UMAT for Isotropic Isothermal Elasticity
Example 2: UMAT for Non-Isothermal Elasticity
Example 3: UMAT for Neo-Hookean Hyperelasticity
A Treatise On Mathematical Theory Of Elasticity
An old book of elasticity with excellent and precise theoretical explanations. It is still valuable and inspiring book in elasticity up to now.

Plasticity and elasticity questions
Dear All
I has question about these stresses.
1.Are deviatoric stress generate plastic deformation?
2. Are hydrostatic stress generate plastic deformation?
3.What is the advantage of transferring strain tenser orientation to the principle coordinate axes?
4. What is the difference between rupture and fracture stress?
Announcing free version of Kalker's rolling contact model
Dear all,
Herewith I would like to announce that we have decided to make our CONTACT software publicly available. You can obtain a free copy at the web-site www.kalkersoftware.org. We hope that the software is beneficial to you. We further hope that you give us helpful feedback in return.
Journal Club Theme of September 2009: Elasticity and Failure
Let us consider interaction of two atoms/molecules/particles. The reference distance between them corresponds to zero interaction force and zero stored energy. The interaction passes three stages with the increase of the distance. At the first stage the force increases proportionally to the increasing distance: the linear stage. At the second stage the force-distance relationship deviates from the linear proportionality: the nonlinear stage. At the third stage the force drops with the increasing distance: the separation or failure stage.
Volume integration in mehsless methods

I use the meshless Galerkin method for 3D simulation of plate movement. This method requires the volume integration over a test domain. Could somebody help me with the volume integration? I wonder if there are standard or open source algorithms that can be used for this problem.
I would appriciate any help.
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.
