The Higher Order Crack-Tip Fields for Anti-plane Crack in Exponential Functionally Graded Piezoelectric Materials Dai Yao1, a, Chong Xiao1, b, Li Shimin2,b 1The Academy of Armored Force Engineering, Beijing, 100072 2Beijing Special Vehicle Institute, Beijing, 100072 adai_yao@sina.com, bchongxiao2005@163.com) Keywords: crack tip fields, FGPMs, eigen-expansion method, anti-plane crack Abstract The near-tip fields of an anti-plane crack in functionally graded piezoelectric materials (FGPMs) are investigated.
It is obvious that the crack tip fields and intensity factors obtained herein provide basic solutions to fracture problems of FGPMs in experimental analysis and engineering practice.
