Definitively solved the problem of measuring residual stress ndt in metals

Definitively solved the problem of measuring residual stress in metals. No more expensive equipment: x-rays. neutron, ultrasound is not reliable, or destructive stain gauge and all equipment or modal analysis that are not absolutely precise and safe

A new discovery has resolved the problem exclusively with the principles of applied mechanics.

The results are that you can check at any point the value of residual stress in the metal with a portable equipment, low cost and easy to use. For more information, relative to the future, to Engineers, Doctors, PhD, Expertise, Authors  Researchers please contact :
