Abstract
Summary An experimental investigation has been carried out to study the plugging capacity of homogeneous aluminium plates in alloy AA5083-H112 and AA6082-T6 subjected to a dropped drill-collar, and to compare the results with corresponding tests on steel plates in grade St52-3N. It has been found that alloy AA5083-H112 is more efficient in preventing plugging than alloy AA6082-T6, and that the weight saving of using aluminium instead of steel is approximately 35% based on the same height of drop.
