摘要
大型通用有限元软件ADINA具有强大的非线性计算能力,广泛用于岩土工程数值模拟分析中.ADINA不仅自带常用岩土类本构模型,同时用户可通过子程序实现本构模型的二次开发.本文详细介绍了一个黏土广义塑性模型及其在ADINA中的二次开发过程,通过三轴试验和土层受荷算例验证所开发程序的正确性和可靠性,所述的二次开发思路可供开发其他弹塑性本构模型时参考.
The software ADINA with powerful nonlinear finite element analysis function is widely used in geotechnical engineering numerical simulation. ADINA comes with many geotechnical material constitutive models. Users can achieve the secondary development of a constitutive model through writing the subroutine. A clay generalized plastic model and its secondary development processes based on ADINA have been particu- larly introduced in this paper. A triaxial test and a numerical example are used to verify the correctness and reliability of the subroutine. In addition, the secondary development ideas can provide references for the secondary development of other elastoplastic constitutive models.
