MultiMechanics is a software company that helps companies using advanced materials greatly reduce physical prototyping and testing, by letting them: (1) predict structural failure based on microstructural design variables, such as fiber orientation and volume fraction; (2) virtually create and test new and existing materials with an unprecedented level of detail and accuracy, for multiple types of composites, including woven, braided, particulate, and chopped fibers reinforced plastics; and (3) zoom into the material microstructure to find out where, when and why damage initiates.

hello ,how can get abaqus plugins??
Hi how to design these voids and simulation, could you help us to do ?
What is the contour plot?
how can i plugin multi mechanics with abaqus
Is there any further tutorial on this topic?
How can I avail this abaqus plugins for my own use?? Is trial version is available?
How much
I'm a graduate student and eager to try this software for my academic project. How can I get it for free? Thanks
Is this first order computational homogenization?
Can you send to me software or a trial version?
Hello Hai, please visit multimechanics.com/request-a-demo/ to request a trial.
@@MultiMechRD Hi, the URL is invalid now, can you send the newest one ?
How to get this MultiMech’s Plug-in?
How is it compared to Digimat?
Hi Ditho, thanks for your question. MultiMech’s multiscale approach (which we call TRUE Multiscale technology) uses FE models as microstructures. This gives the user far more versatility in terms of material design and constitutive modeling. Digimat’s multiscale approach uses Mori-Tanaka as the analytical model for the microstructure. There are multiple assumptions in that model, limiting its versatility. It was originally only meant for materials with ellipsoidal inclusions perfectly bonded to the matrix, so accurate nonlinear material behavior is unfeasible when those assumptions are violated. When comparing both multiscale approaches, there is no question that FE microstructures are more accurate and realistic than any analytical solution, including Mori-Tanaka. The only drawback of the FE method is that it used to take an enormous amount of time to perform. The good news is that MultiMech’s new proprietary data compression technology reduces the computational cost of multiscale FE simulations to the point that they are now practical and the choice between the two approaches is now a no-brainer. In terms of decision/evaluation criteria, speed is fine, but accuracy is final.
Thanks for the Demo, it's very interesting, but how does this Plug-in compare to FE-RVE plug-in available within Abaqus?
hicham farid is there free rve plugin builtin in abaqus?
Yep, there is an RVE plug-in in Abaqus, I'm not sure if it's free or not, I can get that information for you :)
Hi Hicham, great question. The FE-RVE plug-in for Abaqus allows for users to create microstructures and extract the homogenized properties of the composite material. These homogenized material properties can then be used to run linear simulations of a part. MultiMech can also do homogenization, with just as many (if not more) automatically created microstructures. Where MultiMech separates itself is its ability to include damage parameters in these microstructures and simultaneously run the global and local scale models, where each RVE is entirely unique. However, the FE-RVE plug-in and MultiMech can be used in conjunction. MultiMech can import the RVEs generated with this plug-in and with it, run a fully coupled multiscale simulation.
Thank you very much for video. how to model fibers with particular volume fraction...? can you please upload a full video on modeling of fibers in a cube with some percentage...!!
Give send off to plastics.
Future moulding problem solved.
seen this b/4 although i can't recall the company name, but they weave pre-cut blanks of various fabrics for government in ballistic applications.
3D fabrics like "spectra" are cutting edge ballistic protection.?
can you give the download link for this plugin?
Please fill & submit the form www.lanikasolutions.com/contact-form-1/
Cohesive layer mesh is too coarse
Hey very nice and useful tool indeed!! Did you develop on your own? Is it open-source? Cheers
We developed the tool internally. Thank you for the kudos.
Is this showing the compression right after the weaving process has finished, compression during the bake, or something else?
Is there a write-up somewhere with more information about what is being analyzed here? I'm not even sure what part of the gun barrel is represented by the curve or the rectangular items visible at the start of the video.
Are the white areas in the laminate areas of resin richness or voids?
according to a post on LinkedIn, "the plate is 150mm x 75mm x 6mm. The impactor has diameter of 20mm. The plate is made out of glass fiber + epoxy matrix composite."
wonderful!!
