Lee, Edwin Samuel (1943) A correlation of repeated tension impact tests with other tension tests of 17ST duralumin. Engineer's thesis, California Institute of Technology. http://resolver.caltech.edu/CaltechETD:etd-12032008-153139
The strain distribution after repeated tension impacts along the length of several differently dimensioned specimens of 17ST Duralumin is determined for various energies per blow. An attempt is made to determine a relationship between the one energy available per blow, the dimensions of the specimen, and the number of blows required to cause failure of the specimen by repeated tension impacts. A relationship is determined between the percent total elongation and the length-to-diameter ratio. A relationship is determined between the energy per unit volume required to cause failure and the length-to-diameter ratio under static tension, dynamic tension, and repeated tension impact conditions. A “Modulus of Destructiveness" is proposed for 17ST duralumin. A method is presented for predicting the number of repeated tension impact blows necessary to cause failure of a part.
