Study and development on the application of ABAQUS post processor in thin-walled tube NC bending based on Python

Based on an object-oriented program language Python, the ABAQUS post processor was studied and developed to improve the efficiency and accuracy of extracting and analyzing results from nonlinear finite element code ABAQUS. The developing method and general procedure of program development are proposed in this paper. Meanwhile, some post processors were developed for wrinkling judgment, wrinkling areas determination, maximum wall-thinning ratio calculation and location, which give solid foundation to optimize the complex processing. The results indicate that the developed program can extract useful information from mass ABAQUS results efficiently and accurately, and the quantitative analysis and summarization of modeling results can be realized. The study in this paper supplies important instruction to the application of second-developing based on Python in other fields as well.
