Subsequent Yield Surfaces for Annealed Mild Steel under Dead-Weight Loading: Aging, Normality, Convexity, Corners, Bauschinger and Cross Effects.
Abstract
Subsequent yield curves covering all four quadrants of axial stress-shear stress space were experimentally determined for SAE 1017 steel. Initial-yield test results for six different specimens under various combinations of axial load and twisting moments for dead-weight loading exhibited too much scatter to provide a definitive surface. However, after initial yielding of one to five percent a family of small-offset multiple probe yield curves was determined for each specimen. Subsequent curves in a given family of curves were derived from the preceding curves by either strain aging or loadings into the plastic range. Plastic strain increment vectors for zig-zag loading paths were determined. (Author)
