Senstivity analysis according to the geometric change of the stress-concentrated part of round bar with step

단이 있는 환봉에서 응력집중 부위의 형상 변화에 따른 민감도 해석

When the round bar with step is twisted and bent, stress concentration is occurred in the irregular geometric parts. Two dimensional axisymmetric stress analysis is carried out according to the geometric change of the stress-concentrated part of round bar with step. Three dimensional cases are also investigated.
