摘要
本文给出了显含初始条件的、含有两个任意参数的弹性动力学广义变分原理,参数的不同取值以及附加不同的约束条件,可以得到多种显含初始条件的变分原理。
In this paper, an extended form of generalized Variational principle with given initial conditions and boundary conditions explicitly expressed and two arbitrary cons ants contained for linear elas odynamics is developed and various special cases of the principle are also derived.
