fis-1675	Xinhong, Shi; Jianyu, Zhang; Qingshan, Xiao; Tianqi, Liu	Crack initiation and early propagation plane orientation of 2A12-T4 aluminum alloy under tension-torsion fatigue loading including mean tensile stress	2015	8	.pdf	application/pdf	4110	209	54	Although there are two equal values of maximum shear stress amplitude planes and the normal mean stress on both planes is zero, all of the measured angles are in the side of the maximum shear stress plane, which direction is nearly 80°apart with the direction of specimen axial. With increasing of normal mean stress on both maximum shear stress amplitude planes, more cracks are becoming to initial and propagate from the side of maximum shear stress amplitude plane to the other side of maximum shear stress amplitude plane with larger normal mean stress.	cache/fis-1675.pdf	txt/fis-1675.txt
