parallel computing and future
I am new to parralel computing and trying learn basic. wat are the languages can we use for coding in parallel computing. Can any one give me an example for this. Any resource link will do?
Tks in advance

HI all
I am Karthikeyan pursuing my
M.S in Rotating Machinery Design. Its high time for me to take up the
project. So I decided to take my project in Fracture or Fatigue. I am
interested in Thermal fiels also. So I would like to do my project in
Thermal Fatigue fracture side. So I would like to get your suggestions
and some topics to take out work.
I am
interested in coding also so if anybody give guidelines to develop an
element for this analysis then I will be grateful for them.
Hypoelastic-plasticity with logarithmic spin
In small strain elastoplasticity we start off with an additive decomposition of the total strain into elastic and plastic parts. In terms of strain rates we write
Prior to 1990 most large deformation plasticity algorithms extended this idea by postulating an additive decomposition of the Eulerian stretching tensor (rate of deformation):
Derivative of Logarithmic Strain
Some of you probably work on problems that involve moderately large strains. An useful strain measure for such problems in the logarithmic or Hencky strain. In particular, if you deal with the numerics of large strain simulations, you will often need to compute the material time derivatives of logarithmic strains.
Natural Frequencies for all elements in the Periodic table.
Hi,
I am interested to know the natural frequencies of elements in the periodic table. I made some attempt to reveal this information but surprisingly ended with nothing. Perhaps I did not search hard. Does anyone know about the natural frequencies of elements in periodic table.
Sincerely,

Abaqus CAE with dynamic explicit/implict
I want to get the stress value in the roller of a hot/cold worked plate. Both the roller and the plate are defrormable 2D shell model. The change in the thickness of the plate is 0.05mm once the plate passes throguh the rolees.I am trying to use dynamic explicitt in the step process. PLease advice me wat are the other factors i have to input for the dynamic explicit process. I am having some more input for the roller and the plate velocity.
Please advice me or just ask me for further input. Thanks for your mehaniciams feed back.

hi,
I am a Student of 2 year M. Tech. studying in S. V. National Institute of Technology, Surat. My name is Zoeb K Lakdawala. My topic for disseration is ''Implemenation of Fracture Mechanics on Pressure Vessels". In my disseration I want to develop a code on fracture mechanics and compare it with standard Packages like ANSYS & ABAQUS
However, going through the books I have found that in
1. Plane Strain Mode the thickness of the material is very high

An e-book on engineering fracture mechanics
Here is an e-book on Engineering Fracture Mechanics ; you can also download a demo version, the preface, and other related stuff from the page. The idea of the book (as described in the page) sounds interesting:
