Perancangan Alat Uji Impak Digital dengan Metode Charpy Untuk Mengukur Kekuatan Material Polimer

Abstract: AbstrakPada penelitian ini dilakukan pembuatan alat uji impak metode Charpy secara digital dengan menggunakan sensor rotary encoder dan mikrokontroler. Uji impak merupakan salah satu metode yang digunakan untuk mengetahui kekerasan, kekuatan serta keuletan material. Untuk mengetahui keakuratan alat uji impak yang telah dibuat maka dilakukan perbandingan antara alat uji impak otomatis dengan alat uji impak manual. Hasil pengujian menunjukkan bahwa alat uji impak digital otomatis yang dirancang memiliki performa… Show more

“…Figure 4 shows a pendulum used to pound the test specimens and two scale arc needles that serve as angular displacement instructions [10,11]. The impact energy and impact force required to break the test specimen can be calculated using equations ( 1) and ( 2), where Wc is the impact energy, mp is the mass of the pendulum, g is the gravity of the Earth, Lp is the length of the arm, ๐›ผ ๐‘œ is the starting angle of the pendulum, ๐›ผ ๐‘Ÿ is the end angle of the pendulum, acu is the impact strength, b is the width of the test specimen, and h is the thickness of test specimen [12].…”
