Deformation of a sandwich by Ansys
Deformation of a sandwich by Ansys
(OP)
Hello ANSYS forum,
I try to simulate the sandwich model of Torsakul's work for weeks (publications.rwth-aachen.de/record/61754/files/Torsakul_Sirichai.pdf),
Since his model is identical to mine is just another material.
He has calculated the deformation and tension using the APDL, and compared with experimental and analytical solution, it has worked.
Now I come to my question: I have modeled the model as 1/4 model, because I can save calculation time
But I have different deformation than what is prescribed in his work.
With a force of 100 N, my deformation shows a result of 1.1496 mm and with it 0.295 mm
I sent Photos of my Simulation in Appendix to show my results
Can someone please help me with my work please.
PS: On pages 109 and 120, its deformation results
Thank you in advance

yes i model both as Solids.
I tried to model the top and bottom laminates as Shell,but it shows contact problems
I sent the mesh picture in Appendix

might lead to erraneous bending behaviour. You should at least run your model with refined mesh (especially in the thickness
direction) and see how the results change.

If I have understood this well.
Should I construct all 3 layers of sandwich as a shell?
RE: Deformation of a sandwich by Ansys
the top and bottom layers to see that mesh is converging.
RE: Deformation of a sandwich by Ansys
it finally worked out, and exactly how you described it to me. Thank you Very Much
is a deviation of 8% between experiment and FEM poor?
