中文摘要：
讨论了无限长功能梯度压电板中双裂纹尖端热响应分析，将考虑的问题通过Fourier积分变换把混合边值问题的求解转化为裂纹面上位移间断为未知量的3重对偶积分方程，然后利用Schmidt方法来求解，最后通过数值算例讨论了温度及材料系数对应力强度因子的影响．
英文摘要：
Analysis on thermo behaviour of two cracks peak in infinite length of functionally graded piezoelectric board is discussed. By using the Fourier transfirm, the problem can be solved with the help of a pair integral equations in which the unknown variable is the jump of displacement. And then, these equations are solved using the Schmidt method. At last, numerical results show the effect of temperature and material coefficient upon the normalized intensity factor.
