GSA Oasys 8.3 (Structural)
I need some assistance on how to model precast slabs and how to specify the properties of the connecting tie bar for the precast slabs using GSA Oasys.
Help!

Post-doctoral Position in Multiscale Modeling at Caltech
The Center for the Predictive Modeling and Simulation of High-Energy Density Dynamic Response at the California Institute of Technology seeks a post-doctoral scholars in the broad area of multiscale modeling of materials. The scholar will be supervised by Professor Kaushik Bhattacharya, and will develop fast multiscale models that implicitly account for the microstructural features during the dynamic deformation of materials.
Stress-induced phase transformation and pseudo-elastic/pseudo-plastic recovery in intermetallic Ni–Al nanowires
Dear friends,
I want to share our recent research work on NiAl nanowire, which is published in Nanotechnology, IOP publishing. The abstract of the paper is given below. Further details can be found at "Vijay Kumar Sutrakar et al 2009 Nanotechnology 20 295705 (9pp) doi: 10.1088/0957-4484/20/29/295705"
Modelling Impact on ANSYS-AUTODYN OR ANSYS-LS-DYNA
I have one very simple question regarding ANSYS-AUTODYN and LS-DYNA. It seems that both can model impact loads.
My
questions is which can model low-velocity impacts and which can model
high-velocity impacts. I have some troubles modelling low-velocity
impacts in autodyn (changing the mass of the projectile does not affect
the pressure and the stresses on the target. Does this mean autodyn
only models high-velocity impacts)
Large deformation and electrochemistry of polyelectrolyte gels
Immersed in an ionic solution, a network of polyelectrolyte polymers imbibes the solution and swells, resulting in a polyelectrolyte gel. The swelling is reversible, and is regulated by ionic concentrations, mechanical forces, and electric potentials. This paper develops a field theory to couple large deformation and electrochemistry. A specific material model is described, including the effects of stretching the network, mixing the polymers with the solvent and ions, and polarizing the gel.
Some problem concerning the position of increment in ABAQUS subroutines.
Dear all,
I have a puzzling question.
As we know, the positions of a increment in a FEM analysis ( in abaqus) include :
1. the start of the increment 2. the end of the increment 3. the current increment etc
It is easily understood. But the data transfer process in different subroutines have me puzzled.
For example: Subroutines of ABAQUS
Deduction of derivatives of free-energy density function in ABAQUS UHYPER
Dear xuanhe and all,
I have reviewed the paper "Method to analyze programmable deformation of dielectric elastomer layers". (Xuanhe zhao, Zhigang Suo)
It is very insteresting.
I have one question you would like to ask you. Hope to get your reply.
