摘要

美国ADINA R&D公司开发的软件产品ADINA经过20多年的商业开发，目前已成为全球最重要的非线性求解软件，尤其对结构非线性、流-固耦合等复杂问题的求解具有强大优势，被认为是非线性有限元发展方向的先导。然而，任何商业化的有限元软件都不可能满足客户的所有要求，例如，ADINA软件中没有岩土工程领域常用的Duncan-Chang模型。以土工数值分析中广泛应用的Duncan-Chang E-B模型为例，介绍在ADINA软件中进行材料本构二次开发的方法，给出了开发过程，通过对3个常规三轴压缩模型的数值模拟验证程序的可靠性。结果表明，基于ADINA开发的材料本构模型具有计算速度快、精度高和前后处理快捷方便的优点。另外，验证结果也表明该软件具有超强的非线性求解能力和可靠的求解结果。

Abstract

ADINA software

which is developed by ADINA R&D inc.

has become the most important nonlinear finite element analysis software after more than 20 years of commercial development. It is considered to be the forerunner of the nonlinear finite element development and has powerful advantage in solving the complex structure nonlinearity and fluid-structure interaction problems. However

it is impossible for any commercial FEM software to meet all customers requirements; for example

there is no Duncan-Chang constitutive model in ADINA commonly used in geotechnical engineering. Taking Duncan-Chang E-B constitutive model as an example

the methods of conducting secondary development of material constitutive model and the development process are described. Then the Subroutine Cuser3 is verified by simulating three conventional triaxial compression models. Results show that material constitutive model developed in ADINA has advantages of fast convergence

high precision and convenient preprocessing-postprocessing. Results also show that ADINA has powerful nonlinear solution ability and reliable simulating results.
