| Abstract Scope |
The effect of superimposed pressure on, plasticity, localization and fracture of aluminum alloy bars was investigated both experimentally and numerically. An equipment was designed to load dog-bone round bars with high pressure until fracture. Different superimposed pressures were achieved simply through altering the dimension of the specimens. The magnitude of the pressure could reach as high as 3 times of the yield stress (~150MPa). As pressure increased, large longitudinal strain, significant necking, and ductile fracture surface were observed. Finite element (FE) analysis with Gurson’s model, which considers the plastic deformation induced by hydrostatic pressure, was further conducted. Effect of the hydrostatic pressure on plasticity, necking, fracture, and void evolution was carefully examined. Good agreement was obtained for both numerical and experimental results. |
