Abstract
The authors proposed a practical method for estimating 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 measured by strain gages on the boundary. Therefore, in this method, precise estimation of the stress fields can be performed in a real structure whose boundary conditions are hard to grasp. In this paper, we develop this method further so that it can be used for notches under out-of-plane loading or simultaneous in-plane and out-of-plane loading. A straight boundary near a notch and non-symmetric boundary conditions are investigated as factors lowering the calculation precision. Consequently, there is the angular limitation of a notch in application of this method. However calculation results are accurate enough for most cases.
