Hi guys!
I have to define a General Contact with "cohesive behavior". I have to create interaction between 3D solid elements and 1D truss T3D2 element.
I try to create General Contact but Truss elements don't feel the contact vs 3D solid elements.
Someone can help me?
Regards!
 
Can't you use beam elements instead ? General contact should work normally with trusses in Abaqus/Explicit but cohesive behavior is more limited. Which version of Abaqus are you using ?

Of corse I can use beams. Do beams work with cohesive behavior and general contact formulation???

Cohesive behavior should work with node-to-face and edge-to-edge contact interactions with circular beams.
 
I have tried to use beam + cohesive behavior but it don't work.
Can you say the command to use?
I write input file so:

*SURFACE INTERACTION, NAME=CLS_ARMATO
*SURFACE BEHAVIOR, PRESSURE-OVERCLOSURE=HARD
*COHESIVE BEHAVIOR, ELIGIBILITY=ORIGINAL CONTACTS
100000.,100000.,100000.
****
*CONTACT, OP=NEW
*CONTACT INCLUSIONS
ARMATURE,SURF_EXT,SLAVE
ARMATURE,SURF_INT,SLAVE
*CONTACT PROPERTY ASSIGNMENT
ARMATURE,SURF_EXT,CLS_ARMATO
ARMATURE,SURF_INT,CLS_ARMATO
*CONTACT FORMULATION, TYPE=PURE MASTER-SLAVE
ARMATURE,SURF_EXT,SLAVE
ARMATURE,SURF_INT,SLAVE

ARMATURE is surface (type node) of beams, SURF_EXT is surface (type element, faces of 3D solid) of concrete.
Thanks in advance.
 
Are there any warning messages ? Which Abaqus release are you using ? It may not be available in some older versions.
