Maillage incoherence with material properties

Altair Forum User

Hi !

 

I have a problem meshing my geometry with quads, so I did it with triangles. I am doing a simualtion of composie forming and to modelate the resine behaviour i use MAT/LAW59... when i execute the calcul, it stops without erros but with this warning:

** WARNING IN INTERFACE
DESCRIPTION : 
   -- INTERFACE ID : 13
   -- INTERFACE TITLE : Punch-Blank Contact
   DEPTH 0.5000000000000 IS BIGGER THAN THE MINIMUM SIZE OF THE SLAVE SEGMENTS 0.1091826659199
   IN INTERFACE ID=13; PERFOMANCES MAY BE AFFECTED
  POSSIBLE IMPACT NUMBER:           0  (<=           1 *NSN)

 

I looked to the information sheet of the MAT/LAW59 and read that law is only conpatible with 8-noded hexadedron elements (/BRICK)... so I supposed that the problem may come the mon maillage with triangles. Can you tell me if I am right in my supposiions? anf which material law could I utilise to modelise 6-noded triedral elements?

 

Thank you very much!

If I try to do the maillage wih quads this is the error I get :
