Is there any shell element that i can use on rubber material to analyse harmonic behavior?

I have a rubber hose+ complex plastic hose model that i need to analyse on frequence responce analysis. I use tria6 shell element on rubber because its simple geometry and solid tetra20 model on plastic but i cant find a shell tria6 element on element library that use herrmann formulation. Marc automaticly assign thin shell element(element 46 ). I dont know if i can use thin shell element? Does anyone have a clue?

Thanks

Hi,

There is no shell element with Herrmann formulation. It is available for solid and 2D elements ( plane strain / axisymmetric ).

Herrmann elements are developed to handle incompressibility for plane strain, axisymmetric, and three-dimensional problems, so that the element mesh must be able to represent nondilatational (incompressible) deformation modes.
