Purpose: The objective of the work was to construct the finite elements model for simulation of acoustic wave propagation process in polymer material in the aspect of diagnostic of fatigue changes. Design/methodology/approach: Flat model was composed from finite elements with elastic properties of represented medium. Procedure of model modification corresponding with material fatigue degradation was...
Artykuł zawiera przegląd technik badań nieniszczących, ze szczegółową charakterystyką metod termografii w podczerwieni. Opisano te podstawy fizyczne tego zjawiska z wyszczególnieniem metod badawczych oraz charakterystyk oprzyrządowania. W części eksperymentalnej przedstawiono wyniki badań nad możliwością zastosowania nieniszczącej techniki badań termograficznych do wykrywania defektów w materiałach...
