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,
Or,
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.
