3652 平行き裂を有する傾斜機能圧電セラミックス厚板の電気弾性相互干渉(S24-4 特異応力・刃状転位,S24 数理・数値解析による先端材料評価)
詳細
In this paper, the mixed-mode crack problem for a functionally graded piezoelectric material (FGPM) strip is considered. It is assumed that the electroelastic properties of the strip vary continuously along the thickness of the strip, and that the strip is under in-plane electric loading. The problem is formulated in terms of a system of singular integral equations. The stress and the electric displacement intensity factors, and the energy density factor are presented for various values of dimensionless parameters representing the crack size, the crack location, and the material nonhomogeneity.
