Analysis of Thermo Behaviour of Crack Peak in Functionally Graded Piezoelectric Materials
摘要
Abstract
The thermo behavior of crack peak in functionally graded piezoelectric materials is discussed, and the problem can be transformed to a dual integral equations in which the unknown variable is the jump of displacement by using the Fourier transform. And then, these equations are sovled using the Schmidt method. At last, the effect of temperature and material coefficient upon the stress intensity factor and electric displacement factor is discussed by numerical examples.关键词
