three layer rotating concentric cylinder with ANSYS

[eelianx]

Hi, I am modelling a three layer rotating concentric cylinder with ANSYS to investigate the interlaminar stresses. Hence a 3D analysis is unavoidable. It is a solid shell element. Is it possible to model it in one solid cylinder instead of three and define the layers via the section command? Or is section command limited to only defining the layers for each element? I had modelled it via the section command and i realized that the stresses are not correct. i believe the section command only defined the layers for each elements and not the whole section of the model

When modeling it in 3 layers on the other hand, i glued the volumes together but i had problems defining the boundary conditions. the boundary conditions cannot be defined similar to one single cylinder.

i would appreciate any form of opinions, help and tips. as i'm running short on time.

Thanks.

i totally suck in ANSYS. really need some serious help/ suggestion. thank you so so much

The geometry is simple enough that you could probably create the model quicker with just a few NGEN and EGEN commands instead of dealing with the restrictions of using solid geometry first. Then you could select the desired nodes for boundary conditions based on node number or location (NSEL).

thanks for the tips. i will work on it
