Material Type for Plastic Deformation

Altair Forum User

I am trying to simulate a projectile crushing into sheet of thickness 1mm and Ball Dia 20 mm

 

I used material type as ' M2_PLAS_JOHNS_ZERIL'

 

after solution i found that the projectile is unable to pass through the sheet, 

the projectile deforms the sheet extensively but unable to rapture the material

Somebody guide me.

Hi,

 

To simulate the rupture,you should use a failure criteria with material definition.There are some kinds of failure criterion in RADIOSS.

You can refer to help document in the link below and decide to use one of them.

Hello,

 

I forgot to add on previous post;or you can just define the failure plastic strain  under MAT/LAW2 card definiton.

Please refer to link below;
