Introducing: MultiMech for ANSYS

Why MultiMech?

The beauty and curse of composites is that they can be infinitely tailored to fit a specific application.  One can argue that there are as many design variables available at the microstructure level as there are at the part level.  This diversity has proven a formidable foe against standard FEA codes, which were designed and architected before it was worth paying attention to these innovative materials.

What is MultiMech?

MultiMech was the first commercial software to perform efficient "two-way coupled multiscale finite element analysis", where both the part and the underlying material microstructure were Finite Element models being solved concurrently.

Using this technique, MultiMech brings the power and flexibility of Finite Element Analysis to the microstructure level, letting you use realistc representations of your material microstructures, to simulate how those microstructures will affect the linear/non-linear/fatigue performance of your part, and how the loads applied to your part affect its material.  

This full cycle approach, known as TRUE Multiscale™ Analysis, incorporates complex methods for modelling composite microstructural damage and breakthrough techniques for homogenizing and linking the behavior at different spatial scales.   Recently this technology was embedded into the leading CAE platform, ANSYS Workbench.

 

What is MultiMech for ANSYS?

MutliMech for ANSYS is a multiscale plugin for ANSYS Workbench that lets you perform these TRUE Multiscale™ simulations completely within ANSYS, for increased accuracy and productivity. 

fo_fan_375h.pngMultiMech for ANSYS gives you the ability to easily perform nonlinear multiscale progressive damage analysis on ANY type of composite, including:

  1. Unidirectional Composites
  2. Short and Long Chopped Fiber
  3. Woven Composites
  4. Composites with voids, defects, and particulates

In addition, you can easily incorporate manufacturing effects by importing fiber orientation data from tools such as Moldex3d, Moldflow.  

 

What's the big deal?

Incorporating the actual behavior of your composite microstructure dramatically improves accuracy, reducing costs associated with overdesign. With this new approach you can predict the effects of voids, fiber orientation, and manufacturing parameters. Just as important, you can also capture the effect of complex damage mechanisms, such as fiber rupture, resin cracking, and fiber-resin debonding. Since the underlying physics of the problem is directly modeled, on-the-fly, you can obtain accurate structural response without the need of continuous calibration and curve fitting exotic analytical models to extensive experimental data.

The big deal is that the TRUE Multiscale™ approach can:

  1. Save an enormous amount of time and money on upfront design / physical testing
  2. Avoid costly over-engineering and/or part failure
  3. Open up a new design space at the "material scale" where minor adjustments can yield massive performance gains.

All within ANSYS!
