hello all,
will you please tell me, which engine card i should use to see fiber failure, rupture and delamination of composite laminates
and i am not able to see 3D representation of ply thickness, orientation when i do FE modeling for Radioss
HI Rahul,
In RADIOSS it is not possible to visualize the plies as can be seen in OptiStruct.
There are few failure models available (/FAIL) for composite. Please refer to those models.
Thank you so much.
how can i see Strain energy in hyperview?
Hi Rahul,
You can output Strain energy using Control cards>>ENG_ANIM_ELEM>> EPSP.
thank you/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
It is working now. But still it is not giving option to see strain energy in hyperview
Hello prakash,
i have created my composite plate using- Material: M25_COMPSH and Property: P11_SH_SANWD
now i have to use PUCK criteria for impact analysis. where i should define or assign FAIL/PUCK?
Rahul,
Create a property with type as FAIL/PUCK.
I will get back to you with Strain energy soon.
ok but in addition i have to define plies using Material: M25_COMPSH and Property: P11_SH_SANW.
so my question is how can i use both the properties-- P11_SH_SANDW and FAIL/PUCK for same component
Hello Prakash
will you please reply to my above question?
Introduce the /FAIL/PUCK property and refer the material in the new card.
ok i will do it
I am not getting how to assign FAIL/PUCK.
Please help me.
i will try one more time and then i will get back to u
i am not getting
can you share the .out file?
can you check the Tau Max value?
Normal value of Tau Max is 10 times higher than the actual times step should be set in the card directly.
that's okay. but i am struggling to introduce FAIL/PUCK property. I am not able to assign it to component 'XYZ'. i hve already defined comp. 'XYZ' using Material: M25_COMPSH and Property: P11_SH_SANW.
you dont need to assign to any component. Refer the M25 material in the fail/puck property
okay thank you. i will run it
Hi Prakash,
Composite plate is ruptured as shown in pics. But how to see fibre and matrix failures in small particles?
Thanks & Regards,
rahul

And ruptured elements are getting deleted. is there any way to stop it?
Hi Prakash
You are supposed to tell me about strain energy?
Hi Prakash You are supposed to tell me about strain energy?
I am checking with experts on how to output strain energy for composites. I will get back to you soon on this /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
okay i will wait
You can get the output in animation file with /ANIM/ELEM/EPSP
For Law25 this output is plastic strain energy. It is equal to zero when the material is elastic

Sorry here EPSP gives the plastic work.
