This paper proposes an implementation of alternative statistical signal analysis method in characterising material properties of polymer using impulse excitation technique (IET) in accordance with Keywords: M-Z-N; impulse excitation technique; non-destructive testing; material characterisation; vibration signal ABSTRAK Kertas kerja ini membincangkan pelaksanaan kaedah analisis statistik alternatif dalam mencirikan sifat-sifat bahan polimer dengan menggunakan teknik pengujaan impulsif (IET) berasaskan piawaian ASTM E1876. Lima jenis spesimen polimer berbentuk silinder digunakan iaitu akrilik (AC), poli vinil klorida (PVC), polietilena (PE), nilon tuang (MC), dan polioksimetilena (POM). Prosedur eksperimen dilakukan berdasarkan konsep ujian tanpa musnah dengan mengetuk specimen-spesimen tersebut menggunakan tukul impak mengikut julat daya impak yang tertentu
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
