Currently I am doing a comparison results between analytical results and measurement results, I compare stress and strain values in 32 specified locations, unfortunately I found that there are some locations does not give a good agreement. and my professor want me to think about the reason, instead of modifying the model, does anyone come up with an idea about a good reason for this problem? Thank you Cindy

Two possibilities come to mind:

One, the assumptions / theory / model is not describing / modelling the situation correctly,


Two, the source data is incorrect / has an error at those locations - perhaps the sensors are not mounted the same or the mounting points have been damaged / moved or the calibration for each sensor has drifted.

    $\begingroup$ By the way, check and confirm both sides : physical experiment and the model... $\endgroup$

  • $\begingroup$ because now only 6 points show different values, and out of 6 points, only 2 points which show extreme different values. so I start wondering why could that happen and what is the possible reason for this $\endgroup$ Feb 9, 2018 at 6:19
