Thank you so much Sir Best regards.

First, I would like to thank you Sir for the importance that you give to my question. really your answer helped me. The sandwich faces have the same properties (E, G, and PR). If you can give me some references on which you based your answer. So give me some guidance on the helpline that I can...

The core of the sandwich is a Metallic honeycomb (Aluminium), I mean by "PR":"The Poisson's Ratio". Best Regards.

Hi friends, I am looking for homogenized parameters (E11, E22, E33, G12, G13, G23, PR12, PR13, PR23) of a sandwich material orthotropic, can someone help me. best regards.

Thank you so much friends

Hi friends, I need to simulate a nonlinear geometry in Ansys APDL, I use solution control box where I choose "large displacement", is it sufficient? or I have to specify strain/stress variation of material? best regards

I use SOLID45 as element type, is linear. I think that the deflections are those who don't converge. Please Mr. Rick Fischer I need more details, it will be very clear if you show me what can I do step by step, because I'm a new user of Ansys APDL. I don't understand how can I load loadstep 1...

Ok Mr.Rick Fischer, When I apply a force that has a value equal to 100N, I choose the following values ​​in the "Solution controls Dialogue Box": Analysis options: Large Displacement Static Time at end of loadstep: 1 Automatic time stepping: On Number of substeps: 10 No. Max. substeps of...

Hello friends I try to do a nonlinear analysis "using ansys APDL" of a 3-point bending of a beam made in composite materials (face + heart + face). When: The faces and heart are made in isotropic material, I easily obtained the solution without errors. But if: The faces are made in...

Hi friends, I'm trying to simulate a 3-point bending beam, but I don't know the constrain maximum of The elastic zone, I think to solve the problem with nonlinear analysis. Is it the best solution ? Thanks friends.

Hi friends, In bending 3 points (3D), what are the boundary conditions concerning the supports alongside (UX, UY, UZ, ROTX, ROTY, ROTZ) and force applied in the middle. Regards.

ah, ok sir, sorry I didn't understand what did you want Ok, if we take for example the area (59mm*24mm) localised in Y=0, this is the code of meshing of this area: """"""""""""""""""""""""""""""""""" ASEL,S,LOC,Y,0 AATT,1,0.075,1 TYPE,1 REAL,0.075 MAT,1 AESIZE,ALL,ray/4 AMESH,all...

I meshed the entire plate (heart + skins), this is the code: For example: Heart: """"""""""""""""""""""""""""""""""""" ASEL,S,LOC,Y,hp+((1/2)*haut) ESIZE,ray/4 AMESH,all """""""""""""""""""""""""""""""""""""""" skin: """"""""""""""""""""""""""""""""""""""""" ASEL,S,LOC,Y,0 AESIZE,ALL,ray/4...

Thank you very much for your answer Mr. 0rel concerning the value of "PRXZ", when i changed it to 0.5, Ansys mentioned this error "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" ""   Real constant referenced by at least one element types 1 and 2. "" "" "" ""...

Hi friends, I'm a new user of Ansys MAPDL, I'm trying to simulate a 3-point flexion on a sandwich plate, with an orthotropic heart, form honeycomb, and isotropic skins,i entered the properties of each type of material "orthotropic" and "isotropic", but Ansys didn't give me the solution and it...
