Understanding asperity flattening is vital for a reliable macro-scale modeling of friction and wear.In sheet metal forming processes,sheet surface asperities are deformed due to contact forces between the tools and th...
The paper is concerned with the generalization of synthetic theory to the modeling of phenomena such as the Bauschinger negative effect, creep delay, reverse and inverse creep. Detailed calculations of plastic/creep s...
Nanocrystalline copper films were prepared by sputtering and then in situ straining experiments were performed using a trans- mission electron microscope. Macroscopically, these copper films exhibited very low ductili...
In-situ straining SEM observations of an intermetallic Al67Mn8Ti25 alloy were carried out on sheet specimens containing notch with root radius about 100μm. The results show that the crack initiation occurs at notch r...
