| Summary |
"Friction stir welding is an aluminum plate joining process that has been found to be more superior to that of fusion welding. The need for information on this process regarding its response to fracture is vital in understanding the working life of high strength aluminum alloy plate structures in the aerospace industry. The objective of this study is 1) to perform plane strain fracture toughness tests to understand how the friction stir welded material will resist crack growth both in the longitudinal (T-L) and transverse (L-T) planes, 2) to perform plane strain fracture toughness tests through the weak areas of the weld, and 3) to perform tests on fatigue crack growth rates through the weak areas of the welds"--Abstract, leaf iii. |
