Latest Patents

Teodor Dogaru holds a patent for a method titled "Eddy current testing for measuring residual stress around cold-worked holes." This method involves using two identical eddy current coil pairs, each consisting of a driving coil and a pickup coil. One coil pair is inserted into a cold-worked hole, while the other is placed in a non-cold worked hole in a reference material. By activating the coils and selecting an appropriate phase difference between the excitation signal and the output signal, the in-phase component of the output voltage can be correlated to the residual stress around the cold-worked hole. This innovative approach enhances the accuracy of residual stress measurements, which is crucial for various engineering applications.
