INVESTIGATION OF THE COMPRESSIVE, BEARING AND SHEAR CREEP-RUPTURE PROPERTIES OF AIRCRAFT STRUCTURAL METALS AND JOINTS AT ELEVATED TEMPERATURES

摘要

The establishment of the high-temperature mechanical properties of aircraft constructional materials is a prerequisite to efficient design when elevated temperature service is expected. These proper¬ties, which normally are determined from the conventional short-time tensile test and the tensile-creep test, are not necessarily applicable if stress conditions other than tension are encountered. The present program was initiated to examine the high-temperature strength char¬acteristics of a number of aircraft structural alloys when subjected to a variety of stresses under both short and long time loading with the specific purpose of applying these high-temperature characteristics to riveted joint configurations.
