Hello,
When I plot the response acceleration PSD vs Frequency curve, for each frequency there will be an acceleration PSD value. For example, if the frequency range is 1 to 1000 Hz, at 100 Hz, the PSD value is 0.5g^2/Hz. At 500 Hz, the psd value is 0.1 g^2/Hz, and so on. If we are talking about...
Hi Greg,
Thank you for your prompt response. I am fully aware that in the real world situation, most of the structures are non linear, and when excited randomly, it would give results. However, I'm not asking from the real life testing point of view.
I will try my best to explain my question...
Hi,
I am performing a random vibration analysis in LS Dyna. My model has two parts connected by elastic beams. The overall model is linear, but with the introduction of elastic beam connection, this implies nonlinearity.
As the result, I obtained nonlinear solutions. I'm studying the...
Hi all,
I am doing an study on the stress distribution of mechanically fastened lap joint due to secondary bending (tensile loads) for aluminum (plates) and steel(fastener).
To verify with FEA result, I used Hertzian contact stress. However I am encountering a problem. For a "neat fit"...
