stiffness equation meaning in Chinese

刚度方程

This paper studied the material nonlinear problems , geometric nonlinear problems and double nonlinear problems , which includes both material and geometric nonlinear problems , of tall frames . at first i built up the stiffness equations of nonlinear problems by qr - method , then solved them by incremental iterative method , finally wrote the corresponding programs by c and calculated some examples
本文研究高层框架的材料非线性问题、几何非线性问题及双重非线性问题，即既含材料非线性问题又含几何非线性问题，先利用qr法建立非线性问题的刚度方程，然后利用增量迭代法求解非线性刚度方程，并用c语言编制计算程序，计算了一些例题。
The boundary conditions related to electric variables are discussed and this facilitates the solution of global stiffness equation . numerical examples are given at the end of the paper to calculate laminated plates with various kinds of elastic and electric boundary conditions . some results are compared with analytical ones
在此基础上，利用了matlab语言编制了具有一定工程意义的计算机程序，对于各种边界条件以及各种形状的压电层合板和非压电层合板的位移、应力、电势、电位移以及电场强度等做了计算与分析。
