Hello, We would like to create a New Equipment Element in CREO AFX for a customized assembly. The goal is to change the parameters to increase or decrease the size of the assembly. I appreciate any help you can provide. Thanks

Thank you Rick!

Can any one please help me with any literature or information on how to interpret the DMA graphs of thermoset reinforced composites (Storage modulus, loss modulus and Tan Delta). I can upload the graphs we have if that is needed. Thank you

Thank you Burtek. I will try that method. Best Regards

I have a geometry imported from Proe to workbench12. This geometry has multiple parts with varying sizes. I was wondering if there is a way to mesh each part separately or control the mesh on each part. Thanks.

When you use mid-surface and while meshing, select src/trg selection to automatic or manual thin, ANSYS GUI will give you an option between solid and solid shell element. Also try to search about src/trg in ANSYS help for more info. Hope this helps.

If you are using ANSYS design modeler, there is an option to offset the entire geometry/lines/arcs etc.

Dave, I am relatively new to Workbench 12 but when I was exploring for a solution for your case, I found an option but I am not sure if you have already tried that. Go to the tool bar in workbench and in that go to "options" tab and then to "geometry import". There try checking material...

Thanks Geoff. I would give it a try with ALGOR. Basing on your reviews, I feel more comfortable.

GBor, Thanks for your reply. I am interested in doing some linear static analysis as of now. I would be using continuous reinforced composites. My primary concerns are: 1. Layer wise analysis 2. Ease in ply orientations 3. Meshing capabilities 4. Various options to choose failure criteria...

All, I was wondering if anybody can give me a review about using ALGOR FEA analysis for composites. Thanks in advance!

you can purchase it at Society of Allied Weight Engineers, Inc. [sawe-store@sawe.org]. Search for the paper in publications and purchase it online.

ASTM C177 is an easy way to achieve thermal conductivity where ASTM E 1530 is little stringent. I have results of thermal conductivity of composites using both the methods and they are very much similar.

If you are manufacturing UD fiber bars, use pultrusion.You can also make a hand pultrusion unit if you don't require continuous production. It is difficult to make rods using vaccum bagging and achieve better stiffness. Pultrusion yields better stiffness too.

Thank you for your reply. As I mentioned, I am looking for response modification factor for a system built using FRP composite materials but composites are not ductile instead it can absorb some energy before failure. So I thought I should read some background on how I can connect energy...
