摘　　要：ADINA(automatic dynamic incremental nonlinear analysis,ADINA)84作为大型通用有限元程序,具有非常强大的非线性计算能力,广泛运用于各种工程数值模拟分析领域,但对其源代码的解析以及如何运用源代码并对源代码进行二次开发的研究较少。通过对源代码深入解析,基于广义胡克定律编写材料子程序并编译了相对应的求解器,对比验证了求解器和材料子程序的计算准确性,为ADINA源代码的使用提供了详细说明,同时为本构模型二次开发提供参考,为国产专用有限元软件开发提供新的思路。As a large general finite element program,ADINA(automatic dynamic incremental nonlinear analysis)84 has a very powerful nonlinear computing ability and is widely used in various fields of engineering numerical simulation analysis.However,there are few studies on the analysis,application and secondary development of the source code.Through in-depth analysis of the source code,the material subroutine was written and the corresponding solver was compiled based on generalized Hooke's law,and the calculation accuracy of the solver and the material subroutine were compared and verified.The research provides a detailed description for the use of the ADINA source code and a reference for the secondary development of the constitutive model,and provides a new idea for the development of domestic special finite element software.
