Syntaxis for Johnson cooke model

1

Hi!,
I’m trying to use CCX 2.21 with Johnson Cooke plasticity model. This is the block of material that I’m using in the input file:

*MATERIAL, name=mat
*DAMPING,ALPHA=2.5,BETA=0.0
*DENSITY
0.2840
*ELASTIC
2.940000e+07,0.260000,0
*PLASTIC, HARDENING=JOHNSON COOK
83875, 20648, 0.3064, 1, 0.0, 0.0
*RATE DEPENDENT, TYPE=JOHNSON COOK
0.045, 0.015

However, at running, these errors appears:

*ERROR reading *PLASTIC
the name of a Johnson Cook material
must start with JOHNSONCOOK
(blanks are allowed at any location
and the string is not case sensitive)
*ERROR reading *RATE DEPENDENT. Card image:
*PLASTIC,HARDENING=JOHNSONCOOK

*ERROR reading *RATE DEPENDENT
the name of a Johnson Cook material
must start with JOHNSONCOOK
(blanks are allowed at any location
and the string is not case sensitive)
*ERROR reading *RATE DEPENDENT. Card image:
*RATEDEPENDENT,TYPE=JOHNSONCOOK

Then, what is the correct syntaxis for the Johnson cooke model?.

Thanks in advance,

Jack.

Means

*MATERIAL, name=mat

should be for example :

*MATERIAL, name=JohnsonCook_mat

I would say the second error is probably a consecuence of the first.

Thanks!. Now it working. Cheers.
