Vaccum inside hose

Hello,

 

I am thinking of simulating a test for a hose made up of hyperelastic material which will be subjected to -ve pressure to see whether the hose will warp or not.

 

How can I do this? Can someone give me any suggestion on how to proceed? Do I have to use optistruct or radioss or Acusolve?

 

Which material card and properties are required?

 

Regards,

Bharat

    With recent enhancement in Hyperworks Optistruct wrt to Hyperelastic  material you can give a try.Depending upon LBC you can make use of any tool.I dont have any readily available material for above requirement.

    Hello Rahul,

    Thanks for helpful reply.

     

    Can you brief me more about the 'Mathe' card enhancement. Are there any documents available on it? I am currently using HW-13.

    Hi ,

    I am also working on similar project with a vacuum tank made of steel. I also have to apply pressure (both high and low) and check for any leakage and deformation in the tank.

    I think this will go to Radioss, considering the non-linearity with respect to the material as well as geometry (large deformation). I am also going by the same as of now and using monitored volume pressure card for loading the tank where we can provide a curve based pressure loading on the surface .
