Special Paint which can show stress distribution, HELP!!
Special Paint which can show stress distribution, HELP!!
(OP)
I have heard that there is some special paint which is used on the way that some part is painted (e.g. beam) and then loaded by force. WHat happen is that paint change it color and that color spectrum can be compared to some kind of stress comparison chart to evaluate results.
Does anybody know something like this ?

There are two concepts which you may be confusing--there is the concept of photoelasticity, which shows strain distributions in a part comprised of particular materials when subjected to some lights.
There is also the concept of coatings/lacquers which are designed to crack when a particular principal strain is exceeded.
If there exists such a paint as you have described, I would suspect it is in a research phase, or very expensive. But I could be wrong--I haven't done ESA in nearly decade.
