A method of determination of the regular stress term for an arbitrary joint geometry under thermal loading

The problem is treated of a two dissimilar materials joint with arbitrary edge angles under thermal loading. Emphasis is placed on the investigation of the regular stress term, which is independent of the distance r, in the stress field near the singular point. A method of calculating the regular stress term σij0(θ) analytically for arbitrary angles θ1 and θ2 is presented. Numerical results of σij0 for special wedges are included for all possible Dundurs parameters. It is shown that under thermal loading conditions the regular stress term is very important to the stress distribution on the near field of the singularity point. (orig.)
