Help with Optistruct analysis

Hi Amey,

I understood that you have 3D elements in your model and you are trying to assign a system through 2D>> composites which is not valid.

Instead you can orient using Analysis>>System>>Material orientation>> Angle.

You can review material orientation using Orientation Review available in Aerospace profile.

Hey Prakash,

Thanks a lot for the reply,

I did as you mentioned, but my next question is I have to compare the analysis results with different material orientations (which will show the material building direction for additive manufacturing) so how can I get those results using the Optistruct analysis. I tried the above method and then did the Optistruct analysis but I am getting the same displacement and element stress behaviour of the product for the x,y,z material orientation directions, am I making some mistake or this method wont work with Optistruct?

Thanks,

Amey Dholam

Hi @Ameydholam

Can you let me know what type of material are you using?

Meanwhile I will check with an orthotropic material and will update the results to you. 

Hello,

please help me how to apply spring pretension to CELAS elements to simulate vibration analysis of suspension seat.

Hello,

I am using 316L (1.4404) Stainless Steel (MAT1)

Hi @Ameydholam

316L stainless steel is a isotropic material which posses same properties in all directions. right?

Hi @Prakash Pagadala

Yes, it is isotropic material, identical values of properties in all directions

Yes, it is isotropic material, identical values of properties in all directions

So the results will be same no matter what orientation you have.

Okay, thanks a lot. I have another question, is it possible to simulate material building direction (Unlike in mold flow simulation, suppose from x-direction then again with y-direction and so on), I am trying to work on that in Hypermesh with my product. I want to do the analysis of the same product with different material building directions. 

Thanks and Regards,

Amey

Hi @Ameydholam

Not sure what you mean by material building direction, but if you are looking for how much material is required for a structure for a given loadcase, you can do a topology optimization.

By material building direction i mean, unlike in injection molding we can find how the plastic fills the mold. We provide a gate through which the plastic will start filling inside the mold and the product is manufactured, this complete process is simulated and analysed (I have a attached a sample about the same). I am trying to simulate and analyse the same thing here with steel, and this process is called additive manufacturing (3D Printing). I want to know whether it is possible in Hyperworks to do that.

Thanks and Regards
Amey
