Method for Processing Results of Magnetic Testing for Reliable Real-Time Detection of Critical Continuity Defects
Source abstract
Abstract
Inverse problems of magnetostatics for continuity defects can be formulated in different ways. One can set the task of determining defects with high accuracy and resolution or limit the task to revealing several specified types of (“hazardous”) defects with varying degrees of probability. In this case, other real (“minor”) defects will be either skipped by the program or “replaced” by defects from among the ones specified. Minimizing the residual functional between experimental and calculated data is the main task when solving any inverse problems, both in real time and off-line. The paper considers an approach to calculating a simplified inverse problem in real time without accumulating experimental data bases.
