摘要

美国HKS公司开发的软件产品ABAQUS是目前世界上最强大的非线性有限元分析工具之一。该软件包括了众多材料本构模型，但尚缺少国内外土工数值分析中广泛采用的Duncan-Chang本构模型。这一缺憾影响了ABAQUS软件在土工分析中的应用范围。本文旨在介绍ABAQUS中开发Duncan-Chang材料本构模型实现方法，给出了开发过程的概要，完成了两个典型常规三轴压缩模型问题数值测试。结果表明：在ABAQUS中增加Duncan-Chang材料本构模型后，不仅可以充分地利用该软件强大的非线性求解平台，而且还有可能完成复杂土工应力应变的有限元数值分析问题，同时，具有计算速度快、计算精度高和前后处理快捷方便的优点，极大地降低了土工分析程序开发的难度，并减少了维护工作量。

Abstract

The software of ABAQUS

which is developed and supported by HKS Inc.

is currently one of the most powerful nonlinear finite element analysis implement in the world. It includes many different kinds of material models. However

the release of ABAQUS currently absents Duncan-Chang constitutive model that has been widely used to simulate some deformation problems in the field of geotechnical engineering. The shortage limits the software’s application scopes in some extents. In this paper

the procedure and outline to develop Duncan-Chang constitutive model in ABAQUS by using User Subroutine were proposed and implemented. Two numerical examples were also solved and compared with conventional triaxial compression test data. All numerical results exhibit that it will be possible to accomplish some complex stress-strain analysis for soil engineering problems by fully making use of the powerful solving platform after ABAQUS is added Duncan-Chang constitutive model. Meanwhile

there are some advantages of faster convergence

higher efficiency

higher precision and more conveniently preprocessing-postprocessing. The programming difficulties to develop soil engineering and workloads of maintenance are also greatly decreased.
