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.

  • wow.. I like the second option. thank you SolarMike.. I really appreciate that – Cindy.Karina9 Feb 09 '18 at 06:07

    By the way, check and confirm both sides : physical experiment and the model... – Solar Mike Feb 09 '18 at 06:14
  • 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 – Cindy.Karina9 Feb 09 '18 at 06:19
  • You left out the most important possibility: sophons https://en.wikipedia.org/wiki/The_Three-Body_Problem_(novel) – Carl Witthoft Feb 09 '18 at 15:08
