elastic stiffness matrix meaning in Chinese

弹性劲度矩阵(结构分析)

In order to obtain elastic stiffness matrices and geometry stiffness matrices that do not depend on subdivision of the element for convergence , the displacement functions are expressed in terms of the geometry properties of the section and this consideration leads to the formulation of exact stiffness matrices for linear elastic analysis given in this paper
本文利用有限元方法对变截面梁单元进行研究。为了得到精度不依赖于划分单元数目多少的弹性、几何刚度矩阵，本文采用变截面构件几何特性积分所获得的轴向、侧向位移函数。
