S-N curve
I am working on plastic behaviour of metal. I am using Abaqus 6.7 for simulation of uniaxial ratcheting of steel under cyclic loading. Modelling and job submission/completion has been done successfully. But I cann't understand where the data for Stresses(S) & number of cycle(N) is strored to draw S-N curve. Please suggest.
A 3D interactive CAE Knowledge Portal is launched with Social Elements
A 3D Social Net Working Site (http://bit.ly/9yGMrO) was launched for publishing 3D Simulations. It is to 3D Simulations like what youtube is for videos. The teachers / Professors of Science , Engineering, FEA, CFD can download the 3D simulations from here and embedded into PowerPoint slides and show interactive 3D simulations to the students, making the teaching of Science and Engineering very interesting. http://bit.ly/9yGMrO
Tension in screw because of moment in section
Hi,
In a section of a beam with a rectangular hole which has got crack (see attached picture); Moment and shear are specefied. I can undrestand why we have tension in the screw because of the shear but why do we have tension because of moment in the screw? Can anybody explanin me why moment in the section can cause tension in the screw which should be accounted for in the screw design.
Thank you,

Nancomposite textbook for undergrads ? recommend me one.
Dear All,
I've got to start teaching a masters level programme on nanocomposites, well 7 lectures worth of one anyway. It will serve as an introduction to NCs and briefly review the current stat of the art.
I would like opinions on textbooks to accompany such a module.
Any of you had any good experiences with any particular books ?
Thanks,
Chris
Flow stress
Hello
I am working on a thesis project dealing with flow stress in cold rolling, a plane strain operation. To determine the flow stress, tensile tests were carried out. I am aware, that the engineering strain/stress hast to be transfered to the true strain/stress and then the true strain/stress from the tensile test has to be mulitplied with the Von Mises yield criterion to yield the correspondent compressive flow stress in the rolling situation.
Programme of the CONTACT course now available
Dear all,
The programme for the course on "Contact mechanics with the CONTACT software", to be held October 28th-29th 2010 in Delft, the Netherlands, is now available via the registration form on our website www.kalkersoftware.org.

Analysis of grinding using nano cutting fluids with ANSYS.
Hello,
Im doing my M.Tech project on 'Analysis of grinding using nano cutting fluids with ANSYS" . But ANSYS has to work at nano level.. So how to make programming to make ANSYS to use to solve nano level problems.
