The Fluid Dynamics and Solid Mechanics group at Los Alamos National Laboratory is currently seeking outstanding candidates to fill a post-doctoral research position in computational solid/structural mechanics.

The prospective candidate is expected to take part in the development of non-classical, global-local plate/shell finite elements for applications involving the response and/or failure of composite structures under severe dynamic loading conditions.

Dear all,

I'm using LS-Dyna and I would like to model the interaction between a viscous fluid  and metallic substrates.

If everything is working in 3D, it's not the same with the 2D...

Indeed I've used each contact algorithm (I think) in LS-Dyna and each time the contact between my 2D elements and the sph is not initiated.

Does anyone has an explanation to this curious problem ?

Maybe I'm not using the good contact setting.

Or contact between sph and 2D elements is not available in LS-Dyna.

Ionic polymer conductor network composite (IPCNC) is a mixed conductor consisting of a network of loaded ionomer and another network of metallic particles. It is known that the microstructure of the composite, especially that of the electrodes, plays a dominating role in the performance of an IPCNC. However the microstructures of IPCNC have seldom been addressed in theoretical models. This letter formulates a continuum field theory for IPCNC by considering a supercapacitor-like microstructure with a large distributed interface area.

Dear all



I got to model the local buckling in Abaqus, but i do not know how. my model is a profiled steel sheet under distributed load.

does anyone have idea about this?



Thanks in advance

Hi,

I am doing drop test simulation in Ls-Dyna for a transport system consisting of polyethylene foam as cushioning material. Does anybody know damping coefficient value levels for LDPE (Low density polyethylene) foam materials in the range of density of 30-80 kg/m3. 

Thanks in advance
