Condition for Occurrence of Logarithmic Stress Singularity

抄録

The general condition for a logarithmic stress singularities obtained by the author in a previous study is applied to a semi-infinite plate consisting of two-bonded wedges. When the eigenvalue is a multiple root, logarithmic stress singularities then may occur. The results of analysis show that the logarithmic singularities in the stress field may be of order(log γ)², log γ or γ^λ-1 log γ, depending on the combination of materials and the vertex angle of the wedges.
