Abstract

Abstract: This series of papers on behaviour of square sandwich panel consists of two parts. In part I, the performance and behaviour of the square sandwich panel under static loading was first examined. The sandwich panel was centrally loaded by using hemispherical and flat indenters on their respective support units. The panel materials used specifically for this project are mild steel skin and PVC foam namely R55 and polyurethane (PU) foam cores. The aim of this study is to obtain experimental evidence of the failure modes of square sandwich panels under concentrated load at the centre of panels, simply supported at the four edge corners for the square panel. After static tests, the whole curves for each panel were determined. The relation between the observed damage evelopment, the property of degradation during the static test of the panels was investigated. In part II, the dynamic tests will be conducted in order to determine the performance, behaviour, effect of foam’s type and the correlation between input energy from static and dynamic tests.

Abstrak: Kajian mengenai panel apit segi empat terdiri daripada dua bahagian. Dalam bahagian pertama, prestasi dan kelakuan panel apit segi empat yang dikenakan beban statik dikaji. Panel apit ini sokong oleh unit sokongan dan dikenakan bebanan dibahagian tengahnya dengan menggunakan penakuk separa bulat dan penakuk rata. Panel apit spesifik yang digunakan untuk projek ini ialah kepingan keluli lembut, foam PVC yang dinamakan R55 dan teras daripada busa poli uretana (PU). Tujuan kajian ini adalah untuk mendapatkan bukti secara eksperimen tentang corak serta jenis kegagalan panel apit segi empat yang dikenakan beban tumpu di tengah–tengahnya dan disokong pada setiap bucunya. Selepas ujian statik dilakukan, lengkungan bagi setiap panel ditentukan. Hubungan antara pertumbuhan kerosakan dan kelakuan kerosakan semasa ujian statik ke atas panel dikaji. Dalam bahagian kedua, ujian dinamik dijalankan untuk menentukan prestasi, kelakuan, dan kesan bagi jenis busa serta hubungan antara tenaga masukan daripada ujian statik dan dinamik.
