摘要
讨论了一种用以求解粘弹性问题的边界单元法,并给出两个算例。该边界单元法用空间和时间上的物理量来建立边界积分方程,用通常的线弹性静力学边界元法进行求解,不需进行 Laplace 变换和反变换,避免了数值变换和反变换中的种种困难。
New boundary element method with no use of the Laplace transform and inversion transform for viscoelastic problems have been discussed in this paper.Since the boundary element methods presented in this paper are formulated in terms of physical varibles in space and time,the method avoid the inevitably encounters difficulties in inversion of the transformed varibles into the physical ones in the so far proposed boundary element methods.Numerical results are shown for some sample problems to demen- strate the potential usefulness of the proposed method.
