Reply To: Hashin failure criterion

Hi Aurojyoti, 

Thank you for the information, I tried to put the command inside the geometry but it gave me the error:

 TB,FCLI,,,1 has already been defined.  Please delete existing table to  overwrite. 

 

 

 

 

 

 

Here is where the commands are inserted and both the content of two APDL are the same

 

 

 

 

FCTYP, DELE, EMAX, SMAX, TWSI, TWSR

FCTYP, ADD, HFIB

TB,FCLI,1,,16,1,,108000000,29800000,2300000,5500000,,,7800000,7800000

TB,DMGI,1,,,2,,1.6,60,0.06,0.2

These are the material properties I got:

Failure criteria:

Parallel tension = 108 MPa

Parallel compression = 29.8 MPa

Matrix tension = 2.3 MPa

Matrix compression = 5.5 MPa

Longitudinal shear = 7.8 MPa

Transverse shear  = 7.8 MPa

Fracture energy

Longitudinal tension = 1.6 N/mm

Longitudinal compression = 60 N/mm

Transverse tension = 0.06 N/mm

Transverse compression = 0.2 N/mm

I wonder what mistake I had made that cause the error?
