A particular formulation of the finite-element method relevant to the analysis of the Brinell hardness is established. The Brinell hardness of 0.35%C steel and 70/30 brass is analyzed by the proposed method using the stress-strain curve of the tensile test. The numerical results are in agreement with the experimental results within an error of less than 8.9% for 0.35%C steel and 5.8% for 70/30 brass. The extension of the plastic zone induced by the indentation of the indentor is investigated by the analysis. The residual stresses in the specimens after removal of compressive load are discussed. Further applications of the proposed method are also suggested.
