Analysis of thermo-mechanical-electric behaviour of functionally graded piezoelectric piezomagnetic material plate
摘要
Abstract
The thermo-mechanical-electric behaviour of functionally graded piezoelectric piezomagnetic material plate is discussed in the paper. Taking account of the permeable boundary conditions, firstly, the system complex governing equations can be obtained by using the constitutive relations of functionally graded piezoelectric composite materials. Secondly, the Fourier integral transform techniques are used to reduce the problem to the dual integral equations. Thirdly, these dual integral equations are changed into Fredholm integral equations by using Copson method. And then, the numerical integration technique is made use of to solve the integral equations, the stress, electric displacement and magnetic intensity factors at crack tips are obtained. At last, the numerical results show the effect of loading combination parameter, material distribution, the frequency of temperature and material coefficient upon the normalized intensity factor.关键词
