How to choose what kind of element for particular problem (2D plane stress element or 3D solid element)?

Dear all,

I would like to ask expert FEM users that how can we choose what kind of element for particular problem? Such as a plate (thickness t = 2.5 mm, W = 15 mm, L = 64 mm) subjected to axial tensile loading of cyclic loading, I should choose 2D plane stress element or 3D solid element?

It is really appreciated for all suggestions.

Kind regards,

Anh
