Unknown displacement jumps in the equations are approximated with the products of the fundamental density functions and polynomials , in which the fundamental density functions are expressed with exact solutions of the two - dimensional interface cracks due to axial - symmetries of the problems herein 方程中的未知位移间断近似表示为基本密度函数与多项式之积,其中基本密度函数考虑到问题的对称性用二维界面裂纹精确解表示。
Unknown displacement and electric potential jumps in the integral equations are approximated with a product of fundamental density function and polynomials , in which the fundamental density function reflects singular behavior of electroelastic fields near the crack front and the polynomials can be reduced to a real constant under uniform loading 超奇异积分方程中的未知位移间断和电势间断近似地表示为基本密度函数与多项式之积,其中基本密度函数反映了椭圆片状裂纹前沿电弹性场的奇异性,而多项式在均布载荷作用下可用一个常数来表达。
