M. Langseth et Pk. Larsen, DROPPED OBJECTS PLUGGING CAPACITY OF ALUMINUM-ALLOY PLATES, International journal of impact engineering, 15(3), 1994, pp. 225-241
An experimental investigation has been carried out to study the pluggi
ng capacity of homogeneous aluminium plates in alloy AA5083-H112 and A
A6082-T6 subjected to a dropped drill-collar, and to compare the resul
ts with corresponding tests on steel plates in grade St52-3N. It has b
een found that alloy AA5083-H112 is more efficient in preventing plugg
ing than alloy AA6082-T6, and that the weight saving of using aluminiu
m instead of steel is approximately 35% based on the same height of dr
op.
