| description | In this paper, the stress field at the interface corner edge of a bonded cylinder under bending is discussed by comparing with that under tension. Asymptotic description of the stress field under the bending consists of the singular stress term and the non-singular stress term as well as that under the tension. The similarity relation between the singular stresses under the tension and the bending is confirmed by performing 3D FE analyses on the bonded cylinders under the tension and the bending which are subdivided by the same mesh pattern. The ratios of the intensity of the singular stress field under the bending to that under the tension are computed changing material combinations variously, the maximum and minimum values of the ratios are shown in the table and the chart according to Dundurs' parameter (α,β). The intensity of singular stress field for the bonded cylinder cannot be controlled by Dundurs' parameter uniquely. However, because the differences between the maximum and minimum values are small, the ratios can be controlled by Dundurs' parameter. Then, the ratios are larger than 0.7 and smaller than 1.0 in almost all material combinations with α(α-2β) < 0. |
