T-Stress in Piezoelectric Solid
-
摘要: 探讨了横观各向同性压电体平面问题中裂尖的非奇异应力项．利用叠加原理和Plemelj公式，通过求解Rieman-Hilbert问题得到非奇异应力项．结果表明弹性常数，压电及介电常数影响着非奇异应力项的值．当压电材料退化为各向异性材料时，该值与在各向异性材料时所得结果一致．Abstract: The non-singular and bounded terms for stresses near the crack tip were investigated. The crack problem in a transversely isotropic piezoelectric solid for the plane problem was dealt with. The principle of superposition and the Plemelj formulation were introduced. The non-singular terms are given by solving Rieman-Hilbert problem. It is shown that the non-singular terms are influenced by the elastic and electric constants.
