摘要
本文对弹性体振动的模型方程??=-a^2??提出几个差分格式.其中隐格式每计算一个时间层只需解一三对角线方程组,而半隐格式却可利用边界条件显式地计算,且所有格式均是无条件稳定的.
Several numerical solvers for elastomer vibration equations are obtained by solving either a set of three-diagonal linear equations simultaneously or a difference equation explicitly.Other common topics such as local truncation error, stability are also discussed.
