This paper deals with numerical simulations for nonuniform yielding processes in mild steel through use of the finite element method. The yield drop is taken into account in the simulation by means of Hahn's constitutive equation. The yielding processes in straight and notched specimens are discussed based on the simulation. The simulated result agrees well with the actual behavior of nonuniform yielding observed in annealed mild steel. The simulation also shows that the nonuniform yielding phenomenon is relevant to yield-drop behavior of the material element.
