    AFX

    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

    DMA graph interpretation

    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

    Meshing Multiple Parts

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

    Meshing Multiple Parts

    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.

    ANSYS Workbench V12 Shell Meshing

    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.

    Is it possible to offset Curves/lines in ANSYS?

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

    ANSYS MATERIAL IMPORT

    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...

    ALGOR for Composites

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

    ALGOR for Composites

    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...

    Thermal Conductivity - ASTM E1530 vs ASTM C177?

    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.

    Pultrusion or Vacuum injection moulding?

    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.

    Response Modification Factor

    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...

    Response Modification Factor

    Hello, I want to read about response modification factor, significance and factors affecting R value. I need to know how R value varies with material. I am basically looking for composite materials. Can anybody suggest me some books/websites. Thanks a lot,

    Baffle Design

    Bimr, I haven't answered a part of the question you asked. My goal is to build just a wall. So I am looking for thickness values of the wall, shape (i.e. flat surface or curved such as sinusoidal etc.) For purification of water, water inside the tank has to move in a longer path from inlet to...

    Baffle Design

    Thank you Bimr. This is what I am looking for. Thanks a lot again.

    Baffle Design

    Hello Bimr, Thanks for your reply. I am trying to design a baffle which acts as a wall and submerged flow control devices. These can be used for chemical mixers, chlorine tank etc. As I am new to this field, I would like to learn as much as possible before coming up with a design. Thank you.

    Sealing carbon fiber tubes for deep water application

    If you are looking for a good adhesive, try plyogrip from Ashland. It is polyurethane based adhesive and I used that to test composites for tension testing.
