contact print in abaqus

Submitted by RenegadeMaster on Thu, 04/15/2010 - 13:20

When using contact print in abaqus, how it is possible to obtain contact press of slave surface nodes to the dat-file? It is easy to get the results of master surface nodes, but in this situation it is not possible to change slave surface to master surface.

contact between parts

I have modeled a beam column joint with steel and concrete by using 5 parts. Is it essential to give contact between the 5 parts?. How to give material properties for ordinary concrete and fibre concrete?. please help me that how to give reverse cyclic load in ABAQUS.

with regards

Finite-Temperature Atomic Structure of 180^o Ferroelectric Domain Walls in PbTiO_3

Submitted by arash_yavari on Wed, 04/14/2010 - 21:21

In this letter we obtain the finite-temperature structure

of 180^o domain walls in PbTiO_3 using a quasi-harmonic

lattice dynamics approach. We obtain the temperature dependence of

the atomic structure of domain walls from 0 K up to room

temperature. We also show that both Pb-centered and Ti-centered

180^o domain walls are thicker at room temperature; domain

wall thickness at T=300 K is about three times larger than that of

T=0 K. Our calculations show that Ti-centered domain walls have a

super-mechanician?

This month's issue of SIAM news had a beautiful story of how one hard problem in mathematics was solved in less than six weeks using online collaboration. SIAM's story is not online yet, but here is another link to the same story . SIAM news refers to a "super-mathematician" coming out of several individual mathematician spread all over the world.
