基于CalculiX的混凝土本构二次开发

The secondary development of concrete constitutive structure based on CalculiX

本文介绍了以开源有限元软件CalculiX为平台,进行二次开发的基本原理和流程。文中详细介绍了编制符合《混凝土结构设计规范》要求的混凝土本构材料子程序方法。并通过算例试算,验证了子程序的可行性和准确性,表明该子程序可用于混凝土结构的有限元分析,具有工程应用价值。

This paper introduces the basic principle and process of secondary development based on the open source finite element software CalculiX.In this paper,the method of compiling concrete constitutive material subroutine conforming to the requirements of code for design of Concrete Structures is introduced in detail.The feasibility and accuracy of the subroutine are verified by an example,which indicates that the subroutine can be used in the finite element analysis of concrete structures and has engineering application value.
