Viper - 2D Microstructures generation and finite element models in Abaqus

[@abhishekksingh8892]

Lovely presentation and very useful software to work on RVE level simulation.

Thank you!

Hi Miguel, this Viper software seems very powerful for particle type microstructure. It would be great if I can utilize this tool in my research study. Is it possible to share?

[@mherraezmatesanz]

Sure! You can find more details here: materials.imdea.org/viper-virtual-ply-property/

can we generate lamellar type microstructure ? like titanium metal- needle like microstructure? tq

[@divakarraju8423]

Dear Miguel, it is a wonderful tool for the generation of RVE for higher volume fractions and voids. I am also excited to work with this tool. is it possible to share.

Sure, please contact me by email: [e-mail]

Is there any way to access the Viper ?!

Can viper compute elastic properties?

[@mherraezmatesanz]

Viper is intended to obtain the geometry of the material system (made of fibers or particles) and compute its mechanical behaviour using other numerical software like Abaqus. Elastic properties can be computed on a single simulation using Abaqus in a few seconds. For a faster computation of elastic properties let me refer to the FFT method that can be applied on periodic structures (representative volume elements, RVE). You can find a good starting point about it in th following article: T.W.J. de Geus, J. Vondejc, J. Zeman, R.H.J. Peerlings, and M.G.D. Geers. Finite strain fft-based non-linear solvers made simple.
