Hi everybody, First of all I would like to introduce myself, as a new user here. My name is Aleksander Marek and I'm student (3rd year of 1st degree) at Poznan University of Technology in Poland. I'm working on UMAT that accounts for Hoffman Plasticity and all of its simpler forms (Hill,

Is
there any one here who could help me through the step-by-step creating and analyzing
a 3D simulation of ballistic, full penetration impact of a steel, rigid
projectile into the 3D composite plate?



note1: as i know,
available HASHIN damage model in ABAQUS isn't an appropriate tool to do
that. because it has an important restriction that confined you in the
"2D" damage analysis of composites and using 2D planar elements only.



note2: so, my preferred software is LS-DYNA or ANSYS-APDL now.

Dear Mechanician

please find enclosed the announcement of the Workshop in Sandanski.

Dear all,

Where can we find the datum of plastc and damage evolution in uniaxial case for concrete of some specfic strength? It seems that datum associated with plasticity or damage can not be found in concrete code. But when you use the damaged plasticity model integrated in ABAQUS, these datum are indispensible.

I know this  question is a not new one and it has been posted before. But these posts seems not completely answer this question. I tested  for77 and for90 codes for isotropic elasticity respectively. The analysis based on for77 codes runs successfully and the for90 codes can be compiled successfully.  However, the analysis based on for90 codes shows the following warning:

The positions are open in two areas: a) Metallic Materials and b) Renewable Energy

Please visit this link  to see the complete information about the positions.

Before application: informal enquiries can be sent to me at: aortizb [at] gmail.com

Deadline is October 11, 2013. 

Join us to congratulate Professor Kaushik Dayal, from CEE-Carnegie Mellon,  for winning the prestigious Leonardo Da Vinci Award from the American Society of Civil Engineers (ASCE) Engineering Mechanics Institute
(EMI) for groundbreaking research on the interactions between materials
and electromagnetism that can be applied to new technologies for energy
storage and generation.

Congratulations Kaushik!

hi ,

i am working with concrete beam in ansys, i what to konw how to now its failure manner??? ....how to know whether it is shear or flexural or crushing failure??.....and what is the difference between reaching 0.003 for the strain in concrete and not reaching it ???......what is the difference between getting a message said that we have a rigid body motion ......and a message said we have unconvergence solution???.......i have been struggling to find out the answer but i did get no thing yet ....

thanks
