"Magnesium is taking a more prominent position in the structure of aircraft, and because of this, it is important that the mechanical properties of the material be understood more fully. In the high speeds of today, the tendency is toward the use of thick-walled tubing instead of the thin-walled tubing with stiffening structures. For this reason, it is of interest to note the characteristics of thick-walled tubing when subjected to torsion.
This thesis was first suggested by a circular letter on proposed thesis titles from the Commanding General, Air Materiel Command, Wright-Patterson Air Force Base, Dayton, Ohio. When interest was expressed in the thesis subject on modulus of rupture, the Air Force responded by suggesting the investigation of the torsional properties of magnesium alloys in low D/t ratios. Since there is very little published in the periodicals on the subject, a copy of Munitions Board publication was forwarded, which publication was helpful as a reference.
On further correspondence, the Air Force was of assistance in obtaining a classified bulletin from the National Bureau of Standards, and also information was forthcoming on the size of the specimens that could be used. It was suggested that the material tested be either Dow Chemical Company's 0-1 HTA or FS-1 alloy.
The Dow Chemical Company was then contacted and generously furnished the material for the tests, as well as data on the mechanical properties of magnesium alloys in the form of company bulletins"--Introduction, pages 2-3.
