Ansys Ls-Dyna

I am using
Ansys Ls-Dyna to solve a case where a rigid indentor in the shape of bow
penetrates double skinned structural models. I want to use UPF (User
Programmable Features)
in order to define a custom failure criterion. From the “Guide
to Ansys User Programmable Features” I read that the specific subroutine (usrfc6)
for defining custom failure criteria is available only with shell99, solid46
and shell91
. However in Ansys Ls-Dyna, the user cannot use neither of the above
shell elements. The only shell element that is used in explicit dynamics is
shell163. Is there any way to program or use my failure criterion in Ansys
Ls-Dyna?
