Love波冲击下一维六方压电准晶涂层与基底间界面裂纹分析
Analysis of Interface Crack Between One-Dimensional Hexagonal Piezoelectric Quasicrystals Coating and Substrate under Love Wave Impact
摘要
Abstract
Based on the dynamic theory of piezoelectric quasicrystals,the dynamic fracture behavior of the interface crack in the structure consisting of a one-dimensional hexagonal piezoelectric quasicrystals coating and an infinite homogeneous elastic substrate under Love wave excitation are investigated in this paper.The problem is converted into a Cauchy-type singular integral equation of the first kind using the superposition principle and integral transform method.The off-set path method and Chebyshev-Gauss integration formula are applied to solve this singular integral equation,and the dynamic stress intensity factors at the crack tips are obtained.Numerical examples explore the effects of different material combinations,crack sizes,incident directions,and coupling coefficients of the phonon-phason field,as well as the existence of the piezoelectric effect and phason field on the dynamic stress intensity factors.The results show that compared to traditional materials,the aperiodicity and phonon-phase field coupling effects in piezoelectric quasicrystals influence dynamic fracture behavior.This study reveals the unique properties of piezoelectric quasicrystals in fracture mechanics and provides a new theoretical basis for their application in crack and fracture control,with significant engineering application value.关键词
