this code is in Euler-Bernoulli beam. how to modify it and transform to a cantilever beam with a force in the fifth node(free end point).
Main program:
%--------------------------------------------------------------------------
% Calculating the natural frequencies of a cantilever beam...
The purpose of the 1,2,3,4 in boxes at the bottom of the diagram is element.So the bar is with four elements(five nodes).We can try to put the force in this nodes,like in free end point(the fifth node).
hi~I'm Rex.I have a problem,can anyone help me slove it.
The problem is : Draw the mode shapes and get the natural frequencies of the cantilever beam(with a force in free end)
The bar is shown in Fig.1(you can see in )
and it elastic modulus of 200GPa, cross-sectional area of 0.001m^2, and...
