Shaft is a machine element with main function for power transmission. Shaft is often needed in stepped form (change in cross-section). For a non-smooth shaft (stepped shaft), the elementary stress equations are no longer hold for calculating the actual stress as the stress would be higher than the nominal stresses. To relate the maximum stress at the discontinuity with the nominal stress calculated using the elementary stress equation, a factor is needed which is called stress concentration factor (SCF). This paper aims to present an experimental result of stress concentration factor of stepped shaft of circular-to-square cross-section under pure torsion. The results show that stress-concentration factor of stepped shaft of circular-to-square cross-section is slightly higher than corresponding stepped-shaft of circular-to-circular cross section.
