What system or material can I use to properly embed an end of a cantilever beam?

I am studying vibrations in a cantilevered beam. I need this beam to be totally embeded but the results I am getting are not logical. I think this is because the system where it is embeded doesnt...

FRF in matlab using an accelerometer and a hammer?

I am willing to calculate the damping of a cantilever beam by using the Half-power bandwidth method. For that, I need to calculate the FRF where I plot m.s2/N against Hz. I have both the...

How to calculate damping factors for different vibration modes?

I am currently studying the behaviour of a cantilever beam and I need to obtain the damping factor of each mode of the beam. Does anybody know how to do this? I have the time-response of my beam...

How do you get the overall power of wavelets in Matlab?

I have a signal from an accelerometer of a cantilever beam and I did a wavelet transformation of the signal where you can see it in foto1. But in order to study the damping, I need to get the...

In abaqus, in order to analyse the plastic dissipation at the end of a crack, do I need to specify the plastic behaviour of my material?

I'm studying the effects of plastic dissipation in cracks growth, but when I plot ALLPD in the visualization module it's constant at 0. I guess it's because I didn't specify any values in plastic...
