一类算子的正定性
On the Positive Definiteness of a Class of Operators
-
摘要: 本文给出了弹性力学和弹性结构力学中出现的一类十分广泛的算子的正定性的证明。通常遇到的二维三维弹性力学问题,薄板问题等的方程组的正定性问题可以看为它的特殊情形。Abstract: In this paper,a proof of the positive definiteness for a class of operators is given.The operators considered are general enough to include those in two-and three-dimensional elasticity,thin plates and shells as their special cases.
