文章基于Ansys软件提供的二次开发平台,实现了非杆件体系三维有限元分析中空间应力重积分程序的研发,设计了任意截面形状和任意空间放置两种类型的算例对开发方法和程序进行了验证,最后总结了空间应力重积分技术开发的基本步骤和编程要点,为其它用户进行相关开发提供借鉴和参考。
Based on the secondary development platform provided by Ansys software, this paper realizes the research and development of the spatial stress re-integration program in the three-dimensional finite element analysis of the non-rod system, and designs two kinds of examples of arbitrary cross-sectional shape and arbitrary space to develop the method and program Finally, the basic steps and programming essentials of space stress heavy integral technology are summarized, which can provide reference and reference for other users to carry out related development.
