Abstract:
Theoretical and experimental results are presented for plastic flow of axially symmetric notched bars. The slip-line fields have been calculated numerically using the Shield theory of axially symmetric plastic flow. The load factors obtained from the theoretical solutions differ only slightly from those for plane strain conditions. Two sets of specimens were investigated in order to obtain the actual load factors for V-shaped and rounded notches. The agreement between the theory and experimental results is satisfactory. In the last series of experiments the influence of the diameter of the bar outside the notch was investigated and later compared with the theoretically estimated value of that diameter.
