The plastic deformation on the fracture surface is to be correlated with the loading sequence, which contributes to the understanding of crack growth under aircraft loading conditions. Analysis of the data collected will be done and will include identification and quantification of the microstructures studied. Mechanical tests which will be done may include tensile tests and creep tests. Other duties shall consist of data reduction and analysis of mechanical property data using programs such as Excel and Grapher for Windows. Some time may be spent in the testing of metallic materials including tensile and microhardness measurements.
Many decisions require the support of both spatial and temporal data.
Desired Employment Dates are June 1, to May 31, 2000.
