303 The Application of Heating Method to Identification of Uniformly Distributed Residual Stresses

Abstract

In the heating method it become problem that kowledge of temperature distribution and temperature dependent Young's modulus are necessary. In this paper a method to overcome of the problem for the identification of uniformly distributed resiudal stress is concerned with by introducing an analytical model and by solving the resulting nonlinear least square problem by Levenberg-Marquardt method. The validity of the approach is demonstrated by numerical results.
