Purpose: The aim of the work was to find relationship between the ultrasonic wave velocity and the strenght and stess in a polyethylene specimens. Design/methodology/approach: The experiments have been performed in three distinct phases. During the first phase, typical polyethylene was ageing to get different mechanical properties. In the second phase, strength and ultrasonic properties of composite was testing. In the last of phases we compare changes of properties. Findings: The experimental results showed relationship between velocity of ultrasonic wave and strength and stress in a polyethylene specimens. Research limitations/implications: In the future test will be necessary to use more precise testing equipment. Perhaps we will use other ultrasonic probes of lower frequency. In this experiment we used 2 Mhz probes. It is necessary to run an experiment with more specimens. Further work is needed in the correlations between ultrasound and stress area. Practical implications: The results of the investigation have shown possibility of using ultrasonic method to diagnosis of strength changes in polymers materials. This method allowed to test working parts of machines or buildings, without destruction. Originality/value: The results of the investigations allow to confirm, that ultrasonics can be used to nondestructive testing of the strength and Young's modulus changes.
