As a lead-in to the use of 5083 for liquefied natural gas tanks [1], a special series of fracture tests was ran to substantiate that the alloy has high tear resistance in the relatively thick sections in which it would be used in the structure. These tests were similar in nature to the tear tests which have been made for years [2], but covered a much wider range of variables, viz., (1) much thicker material., (2) specimens from the heat-affected zone as well as the parent metal and the welds, (3) welds made automatically, semiautomatically, and in different positions (flat, vertical, horizontal), and (4) welds in extruded shapes as well as plate. The purposes of this paper are to describe the test procedures, present the results, and discuss their meaning as an indication of the toughness of 5083 for engineering structures.
