摘要
利用分离变量法得到了三维调和函数的一般表达式 ,进而采用Papkovich_Neuber通解与广义变分原理 ,构造了弹性力学三维问题的一类通用半解析数值求解格式 .
A general expression of three dimensional harmonic function is derived by means of variable separation. Based on this result, also in the light of the Popkovich_Neuber solution and the generalized variational principle, a semi_analytical numerical method for solution of three dimensional problems of elasticity is formulated.
