Closed form solution of stress and strain concentration factors of axially symmetric bodies with small scale plasticity by means of the conservative integral method

nservative integral of axially symmetric bodies is established and applied to the determination of stress and strain concentration factors. Under the condition of small scale plasticity, a closed form solution of the above two factors can be obtained with given elastic stress concentration factors for arbitrary hardening materials. It can be verified by calculations that the results given by this method agree with the average values given by Neuber’s method and other empirical formulas. The computations in this method are very time-saving and can be carried out even by calculators.
