Unable to get Damage contour for impact simulation .

Steel ball is impacting an assembly having Aluminum and steel components.
I have modelled the assembly using Shell mesh. the impactor is meshed using 3D elems.

I am using MAT36 law for aluminum and M2 law for Steel maetrial.
I have used ANIM/SHELL/DAMA card .
In simulation results the elements are being deleted but on damage plot it shows no value .
I have used plastic strain vs strain curve for Al .For steel I have defined EPSP_max
How to solve this issue

Hi Anubhav,

Thank you for reaching out to us with your question! My name is Nolan and I will be helping you with this request.

/ANIM/SHELL/DAMA will only show the accumulated damage for failure defined via /FAIL cards.
Damage associated with failure defined directly in Law36 will not be visible in the contour plot.
How are you defining the failure in the aluminum material?

Thank you,
Nolan

Hi,

In /H3D outputs, one can use /H3D/SHELL/DAMG/ID=<mat_ID>/NPT=ALL or /H3D/SHELL/DAMG/ID=<mat_ID>/MODE=ALL/NPT=ALL, that is outputting damage modes for the given material mat_ID as global damage or for each damage model.

It is available from Radioss v2024.1 and for LAW36

Regarding H3D outputs, see
