摘要
:本文分析了粘弹性材料的应力应变关系 ,导出了粘弹性单元的刚度矩阵 ,该刚度矩阵便于用直接刚度法装配结构刚度矩阵。文中还给出了改写后的动力方程 ,这种动力方程非常适合在设置粘弹性单元的结构中进行时程分析。
In this paper,we have analyzed relation between stress and strain of viscoelastic material, founded stiffness matrix of viscoelastic element. This element stiffness matrix is easy to assemble structure stiffness matrix by directness stiffness method. We have presented the rewrited dynamical equation, that is fit to process course analysis in the structure with viscoelastic element.
