Cantilever Beam FE
Cantilever Beam FE
(OP)
Hi
I've been trying for some time to develop a FE model using Mathcad that will use a variable stiffness matrix. I have written a basic FE calculation that provides me with values that correlate well with the classical approach; however, ideally I want to be able to update the beam bending stiffness depending on the calculated curvatures ie the beam gets stiffer as a certain beam curvature is achieved. Non linear I guess.
If anyone has any ideas, or has came across anything like this before, your input would be much appreciated. Thanks
