Abstract Scope |
For decades, Prof. Wayne Jones has worked on many areas related to the mechanical behavior of materials. Some of his most important contributions have been in the area of fatigue of lightweight materials. Advances in experimental methods, analytical techniques, and computational approaches, have now enabled the development of in situ techniques that allow us to probe the behavior of materials in real-time. In this talk, I will describe experiments and simulations that address the critical link between microstructure and fatigue behavior of metallic materials, by using a three-dimensional (3D) virtual microstructure obtained by x-ray synchrotron tomography. The approach involves capturing the microstructure by sophisticated in situ testing in an x-ray synchrotron, followed by x-ray tomography and image analysis, and 3D reconstruction of the microstructure. Fundamental damage and crack growth phenomena in aluminum alloys and their composites under cyclic loading and in a corrosive environment will be presented and discussed. |
