Hey,
I have a question concerning eigenfrequencies:
Let us assume we examine a beam that is fixed at one end and free at the other end. It is possible to get an analytical solution in form of a unlimtied series: sum_i=1..infinity eigenfunction(i)*exp(i*eigenfrequencie(i)*t). (something...
Hey guys,
if I consider a Bernoulli-Beam with a constant jump in cross- section as shown below
Then I get the two differential equations for the bending mentioned above.
Let us now assume that a traveling wave from the left w_incident = C*cos(k_1*x - ωt) arrives at t = 0 at the jump of...
Hey,
This is my first post so I am hoping to do everything right :-)
I do not understand the physical meaning of a complex wavenumber. I understand that, with a general approach u(x,t) = Re(A*[e][(i(kx-omega*t)]) and a complex wavenuber that the wave is decaying exponentially with x. What...
