MATHEMATICAL MODELING FOR THE DEVELOPMENT OF NEW METHODS OF NONDESTRUCTIVE TESTING

A new approach to the analysis of experimental data for non-destructive testing, based on the effect of A. transformations is presented. The results of mathematical modeling of wave process in an environment with a given geometric size are shown

Use of Simulation Methods of Wave Processes for Non-Destructive Testing of Concrete Products of Different Geometrical Size

Theoretical and experimental research of electrical responses under pulsed mechanical excitation of different size concrete products was carried out. Comparison of calculated and experimental data shows very close agreement. The obtained results will help to develop new opportunities to improve the method of non-destructive testing of concrete by creating a bank of calculated electrical responses from products of different geometrical arrangement and elastic response and using them as standard samples for defectiveness evaluation of products according to previously established criteria
