Determination of Optimal Nondestructive Technique (NDT) Using Multi-Criteria Analysis


Article Preview

The present paper presents an optimization model for quality control of industrial products by using two non-destructive techniques (NDT): infrared termography and ultrasonic methods. The main purpose it is to determinate the best analyzing method using multi-criteria analysis by taking into account the results that outcome from the two non-destructive evaluations. There have been studied defects like: internal defects and surface defects. Therewith were taking into consideration: safety, efficiency of the method and the cost of the equipment used in controlling the product. For this study it was created a concrete slab with embedded defects which had different depths. The sample was tested using active thermography and impact echo methods and the results were studied and integrated in an multi-criteria analysis to reveal the best method for this case.
