Abstract
Ultrazvuk se koristi u razne svrhe u različitim granama industrije zbog svoje preciznosti, brzine i mogućnosti nenarušavanja svojstava materijala koji se ispituju. U ovom radu se analizira koeficijent prigušenja ultrazvučnih valova u čvrstom tijelu. Ultrazvučnim ehoskopom se odredi amplituda reflektiranog ultrazvučnog vala koji prolazi kroz akril. Mjerenja se vrše na tri uzorka akrila različitih duljina kroz koja se reflektiraju ultrazvučni valovi s tri različite frekvencije. Obradom i usporedbom podataka se uočava da porastom frekvencije ultrazvučnog vala raste koeficijent prigušenja istog uz manja odstupanja. Do odstupanja je moglo doći zbog nepreciznog izmjenjivanja uzoraka akrila, očitavanja amplitude s grafa te zbog moguće nepreciznosti mjernih uređaja.
Abstract (english)
Ultrasound is used for various purposes in different branches of industry due to its precision, speed and the ability to non-destructively examine material properties. This study analyses the attenuation coefficient of ultrasonic waves in a solid body. The amplitude of the reflected ultrasonic wave passing through acrylic is determined using an ultrasonic echoscope. Measurements are conducted on three acrylic samples of different lengths through which ultrasonic waves of three different frequencies are reflected. By processing and comparing the data, it is observed that as frequency of ultrasonic wave increases, its attenuation coefficient also increases with minor deviations. Deviations may have occurred due to imprecise handling of acrylic samples, amplitude readings from the graph, and potential inaccuracies in measurement instruments.
