摘要
讨论了屈曲特征值问题的定解条件 ,建立了相应的具约束的积分方程组及带Lagrange乘子的边界变分方程 。
The conditions for determining solution of buckling eigenvalue problem are discussed. The corresponding system of integral equations with constraint conditions and boundary variational equations with Lagrange multiplier are established. The theorems on the existence and uniqueness of the solution for these problems are given. The corresponding boundary element method is constructed and the error estimation for the approximation solution is obtained. Finally the numerical example is given.
