Reduction thickness in 3D FEA model

Reduction thickness in 3D FEA model

Reduction thickness in 3D FEA model

Hi all,

thanks to those who responded to my previous query. Your answers, however, let me think of another issue I would like to ask about.

I would like to simulate my example with a 3D FEM code. This code works very well, but it is quite computationally inefficient. Therefore, I would like to reduce its thickness in the 3D model at the minimum, to reduce the computational cost.

What should I apply to the model in order to obtain realistic results and "equivalent" to those I would obtain with a model with real thickness?

Many thanks!

RE: Reduction thickness in 3D FEA model

Are you talking about shell elements?

RE: Reduction thickness in 3D FEA model

Yes, you could reduce a 3D model into a 2D or engineering element model, depending on your geometry and working loads.


RE: Reduction thickness in 3D FEA model

the solutions for 2D elements is well understood and readily available (see FEA texts). A "problem" for you is that for 3D elements each node has 3 (translational) degrees of freedom, but in 2D (and 1D) elements there are 6 (translation and rotation).

another day in paradise, or is paradise one day closer ?
