| 摘 要： | 通过改造均质体边界积分方程，对分区粘弹性介质的全定义域建立位移反分析边界积分方程及数值求解格式。其具体做法是：在满足分区介质的边界条件和区界联接条件下，均质体边界积分方程中引入虚拟力影响项；用样条函数把分区介质的边界积分方程离散化。由此简化了分区问题反分析计算程序，使之与求解均质问题的计算方法趋于一致 |

| Abstract: | Byreforming the homogeneous boundary integral equations, the numeral solution from ofinhomgeqeous viscoelastic medium is established in this paper. The way is as following the fictitious force which is equal to the influence of the inhomogeneous medium isstretched in the homogeneous boundarg integral equations. It meets the needs of theboundary and region conditions of the inhomogeneous medium. The algebraic equation isdispersed through the use of spline function. The Inverted analysis calculating procedureis simplified largly and reaching unanimity to solve the problem of homogeneous medium. |
