Fourier Transforms to find phase angle and time delay of 2 signals

Hi, I have two signals, one is a strain signal, and the other is the corresponding stress signal. I want to find the phase angle and time delay between the two signals. I have a sampling rate of 50 Hz. The frequency of the data (peak to peak) is 0.0666 Hz. What I'd like to do is plot the phase angle and the time delay, and find the phase angle and time delay at my frequency of 0.0666 Hz.

Thanks

I have a similar problem. Did you ever find a solution?
