Impact Analysis using HyperMesh & Radioss

Rajesh Shetty_21146

Hello all,

I'm performing an impact analysis in HyperWorks using Radioss profile. My query is regarding the postprocessing the damage area in HyperView.

Impact analysis -> impact of a composite plate using spherical steel ball

While setting up the solver deck in HyperMesh (Profile: Radioss), I have used the following control cards to evaluate the damage areas:

/ANIM/BRICK/TENS/DAMA/

/ANIM/BRICK/DAMA/

While postprocessing, in HyperView, I can see only the damaged elements (deleted elements) on the composite plate. I can't see the display of damaged area in the legends. My query is, how to measure the damaged area on the composite plate. Is there any control cards I can use to measure the damaged area ? Can we see the damaged area in the legends ?

Thanking you,

Hi Rajesh,

/ANIM/BRICK/TENS/DAMA is only compatible with concrete material law (/MAT/LAW24). So it is expected you don't see anything with composite. 

 

/ANIM/BRICK/DAMA should work if you have a failure criteria defined (like /FAIL/HASHIN for instance). 

 

In order to answer to you as best as possible could you please answer to the following questions:

• What is the material law you are using?
• What is the damage model you are using?
• What is the element type you are using?

Thanks !

Regards,
Mathis.

Hello Mathis,

Greetings!

Thanks a lot for your reply.

• What is the material law you are using?

/MAT/LAW25 (COMPSH)

• What is the damage model you are using?

/FAIL/HASHIN

• What is the element type you are using?

BRICK ELEMENTS (HEX8)

Few composite plates are made of only unidirectional or woven plies

And, few are the combinations of both unidirectional and woven plies
