for analysis the ultimate strength of a stiffened plate damaged with warhead explosion,i need to model a real fragment shape and....
how can i modeling a real fragment(due warhead explosion) impact with abaqus?
just use the proper damage algorithm and fallow the usual simulation. I can suggest you check this website, it has the most complete tutorial on damage simulation I've ever seen.

dear mehdi
thanks
but the shape of fragment(warhead fragment or any other) has the random shape and size, and shape of this object change the failure model response.
have you any suggest about this modeling with abaqus?
what is the difference between the standard shape of bullet like as cylinder or sphere vs real fragment in failure response of metallic target?
Use SPH(Smoothed Particle Hydrodynamics) in Abaqus
Hi every body I have some explicit analysis on plate under impactor. I need to extract the damaged elements in end of analysis with using python. who can explain this for me?
