stress, σ. The flow of aluminum during extrusion is intermetallic shear flow. The significant difference in the shear flow of aluminum com-pared with other metals being extruded is that the center of the alumi-num billet is extruded first, and the peripheral part of the billet flows later, causing more severe shear deformation. As soon as the ...

On the Statistical Size Effect of Cast Aluminium

Manufacturing process based imperfections can reduce the theoretical fatigue strength since they can be considered as pre-existent microcracks. The statistical distribution of fatigue fracture initiating defect sizes also varies with the highly-stressed volume, since the probability of a larger highly-stressed volume to inherit a potentially critical defect is elevated.
