ADINA software, which is developed by ADINA R and 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.
