11. Using the finite element method

In 9 we showed that the calculation of eigenmodes of continuous systems quickly becomes complex beyond the second mode for beam vibrations, even in the simplest cases, i.e. isotropic materials remaining in the elastic domain, constant transverse dimensions, low deformations, restricted boundary conditions, etc.

The most common method for furthering both static and dynamic calculations is the finite element method, which can be used to calculate structures...
