hello everyone,

I model a reinforced concrete Beam column Joint in ansys .total 32 number of load steps inthe 20th load steps  the below error was appear .

Please guide me That Error What's meaning ?

 The supplied nonlinear material properties produced an incorrect       

 material tangent matrix.  Please check your TB input carefully.  A     

 very small yield stress may cause this failure.

thanks and regards

The inaugural HF2013 conference aims to advance the effectiveness of hydraulic fracturing for the energy producing and mining industries and beyond.

It is co-organised and sponsored by CSIRO, the University of Utah's Energy and Geoscience Institute, the International Society for Rock Mechanics (ISRM) and the Australian Geomechanics Society (AGS).

A 1-1.5 year postdoctoral position on the subject "Modeling of contact in parallel computing" is open at Centre des Materiaux, MINES ParisTech.

Dear Colleagues,

At https://sourceforge.net/projects/cmcodes/ you will be able to download open source software for the extended finite element method, the extended element-free Galerkin method and extended isogeometric analysis methods in 2D and 3D.

Some of the papers associated with these pieces of code are here:

Hi all,

In the course of our project, we are monitoring the corrosion behavior of steel reinforcement in cracked concrete, while exposed to simulated sea water. Recent results are posted on our blog,  http://microlab-m3c4.blogspot.nl/ ! Be sure to check them out! For more information, you can contact us, or follow us on twitter @MicrolabM3C4.

Cheers!
