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

A postdoctoral/PhD position in various non-equilibrium problems in solid mechanics is available at the Weizmann Institute of Science. Candidates should have a strong background in physics and/or theoretical mechanics, as well as experience with analytical and computational methods for solving partial differential equations. More details can be found in http://www.weizmann.ac.il/chemphys/bouchbinder/ For information about specific research projects, please send CV, a publications list and a statement of research interests to Dr.
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
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.

Nanovea is proud to announce the installation of a Nano/Micro Mechanical Tester at Technische Universitat Munchen (Technical University of Munich, DE). The instrument was installed in the Department of Civil Engineering & Surveying at the CBM Center for Building Materials. The unique Nano and Micro modular capabilities of the Nanovea Mechanical Tester was chosen over several competitors. The instrument will be used to further industrial research in the mechanical behaviors of concrete and cementitious binder technology among others.

Lecture 1 introduced the crack bridging model. The model is also known as the cohesive-zone model, the Barenblatt model, or the Dugdale model. The model consists of two main ingredients:
Dear All,
In one of my elastic-plastic simulations, I have used the Combined hardening model with half-cycle to model its plastic behaviour. So, I've fed in a list of values from experimental data. Now, I understand that ABAQUS uses certain parameters to generate the stress-strain curve from the data that I've provided.
Is it possible to find out these parameters used by ABAQUS?
Thanks in anticipation,
Aneesh
