element type

[S0606]

Hello,

What is the best element type to use in modelling a pipe which undergoes tension, bending and torsion.

Does it have any contact surface?

 

[S0606]

hello,

yes there are two contact surfaces one with soil and the othe a smooth surface.

 

[Yoman228]

4 layers of C3D8R if you want to use soild.

or

Continuum shell SC8R

 

[S0606]

hello Yoman228,

why do you think Continuum shell SC8R is suitable in this situation.

thank you

 

[Yoman228]

So you do not need to define the mid wall contact surface.

 

[Yoman228]

Almost fogot, if you only intrested in studying the global respone, then PIPE31 or PIPE31H will be fine.

thank you Yoman228 for clarification.
