Deformable Barrier Material Properties

Altair Forum User

Hi,

Is there a Radioss deformable barrier model for offset/side impact available to download like the one shown in this video (1:49:47) -

 

If not, where could I find the properties for this aluminum honeycomb material?

Thanks,
Arjun

Hi Arjun,

 

You can model a deformable barrier. I would suggest you check with suppliers for Aluminium honeycomb material properties.

Hi Prakash,

 

I have modeled the barrier, but for the Honeycomb (MAT28) material I have to input a total of 6 tensile and shear stress functions which I do not have access to.

 

I'm assuming these crash barriers are made from a standard (or at least similar) material. Is it possible to share the properties used in your training seminar I linked earlier?

 

Thanks,

Arjun

Hi jarjun,

 

I suggest google searching for relevant research papers and thesis.

You can find simplified material properties on page 29.

The tensile and shear stress functions can be found in

Hi,

 

in this automotive webinar it is mentioned there is a safety database including dummies and barriers. How to access this content?
