在过去的十年中，非连续变形分析（DDA）社区的研究人员已经投入了大量的精力，通过执行验证研究来记录该方法的准确性。本文总结了100多项已发表和未发表的验证研究，这些研究包括作者可以访问的DDA验证信息。这些研究分为三大类：（a）对分析解的验证，（B）对其他数值技术结果的验证，以及（c）对实验室和现场数据的验证。描述了三种通用的验证技术：定性评估，直观地检查模拟的运行时行为;半定量评估，比较模拟的数值结果;定量评估，其中数值模拟结果与类似的分析、实验室或现场结果进行详细评估。我们发现，在这次审查中的论文所解决的许多问题，DDA执行超过足够的工程分析。版权所有© 2006约翰威利父子有限公司。
Over the last decade, researchers in the discontinuous deformation analysis (DDA) community have dedicated a great deal of effort to document the accuracy of the method by performing validation studies. This paper contains a summary of more than 100 published and unpublished validation studies which comprise the body of DDA validation information to which the authors have access. The studies are grouped into three general categories: (a) validation with respect to analytical solutions, (b) validation with respect to results of other numerical techniques, and (c) validation with respect to laboratory and field data. Three general techniques for validation are described: qualitative assessment visually examining runtime behaviour of simulations, semi‐quantitative assessment comparing numerical results of simulations, and quantitative where numerical simulation results are evaluated in detail with respect to similar analytical, laboratory or field results. We find that for many of the problems addressed by the papers in this review, DDA performs more than adequately for engineering analysis. Copyright © 2006 John Wiley & Sons, Ltd.
