Experimental characterization of interlaminar fracture toughness of composite laminates assembled with three different carbon fiber lamina

Domenico Gentile

In the present work, the fracture resistance of a carbon fiber composite under mode I and mode II loading have been experimentally determined. For the mode I and II, the energy release rate G has been determinate for each material. In some…

Fatigue crack paths and properties in A356-T6 aluminum alloy microstructurally modified by friction stir processing under different conditions

A. Tajiri, Y. Uematsu, T. Kakiuchi, Y. Suzuki

A356-T6 cast aluminum alloy is a light weight structural material, but fatigue crack initiates and propagates from a casting defect leading to final fracture. Thus it is important to eliminate casting defects. In this study, friction stir…
