Abstract

The authors proposed a practical method for estimating the stress fields near a notch in a real structure under in-plane loading in the previous paper. In this method, boundary conditions of a region near a notch are determined reasonably, using the stress field expression and stress components by strain gages on the boundary. Therefore, in this method, precise estimation of the stress fields can be performed in real structure whose boundary conditions are hard to grasp. In this paper, we have developed this method so that it can be used for notches under anti-plane loading or both in-plane and anti-plane loading. A straight boundary near a notch and non-symmetric boundary conditions are investigated as factors lowering the estimation precision. Consequently, there is the angular limitation of a notch in application of this method. However estimation results accurate enough for practically were obtained in the most cases.
