Yes, the test data is the engineering stress- strain relationship.

 

Since you have obtained directly from the test, you can use the same in LAW 33 material model.

Hi,

 

 

 

 

Maybe you have to play with solid element properties.

 

 

 

 

 

Try this: Isolid=1

 

 

Ismstr=1

 

 

Iframe=1

 

 

IHKT=1

 

 

 

 

 

If that doesnt work, use Isolid= 17 and try again and let us know your findings.

 

 

 

 

 

Also, LAW70 needs engineering stress-strain data. Please note this.

 

Hi Prakash,

From the reference manual, the IHKT parameter only works for Isolid=24 not for Isolid=1. Iframe parameter only works for Isolid=1,2,12,17, and it seems that Iframe=2 is recommended.

Hi @Truc

The problem could be with the material or the property. Please share the entire .out file.
