Nondestructive characterization of materials with variable properties

Materials with continuous variable properties in time and space are considered. The possibility of nondestructive characterization of these materials on the basis of nonlinear longitudinal wave propagation data is discussed on the basis of recent results. The model direct and inverse problems are so...

Zusammenfassung:	Materials with continuous variable properties in time and space are considered. The possibility of nondestructive characterization of these materials on the basis of nonlinear longitudinal wave propagation data is discussed on the basis of recent results. The model direct and inverse problems are solved. The utilization of obtained results enables one to solve several nondestructive material characterization problems.
