保存積分を用いた3次元ピエゾ接合体の界面角部近傍の応力特異線上の特異応力の強さの評価

抄録

Singular stress fields in three-dimensional piezoelectric bonded joints with multi-terms of singularities are investigated. The conservative integral formulation is developed for calculating the intensity of singularity at a point located on the singular line (along a free edge). The intensities of singularities at several positions along the singular line of the interface are examined.
