重评儒家的义利观

儒家义利观经历了从“重义轻利”到“存理灭欲”的发展过程。儒家义利观在处理个人与他人、个人与社会的关系方面有某些可取之处，但它的动机是反动的，认识是唯心的，实践是有害的。儒家义利观不能，也不应该成为现代社会的道德规范。     

如何加强和改进思想政治理论课实践教学环节

由于种种原因，致使高校思想政治理论课实践教学没有行之有效地开展起来，严重制约了思想政治理论教育教学的效果。通过建立实践教学领导体制，加快社会实践课程化建设步伐，设立专项基金和完善实践教学保障机制，加强和改进思想政治理论课实践教学环节。同时要把理论教学与实践教学结合起来，使思想政治理论课更有时效性。

A constitutive model coupling damage and material anisotropy for wide stress triaxiality

A constitutive model that can describe the damage evolution of anisotropic metal sheets during the complex forming processes which experience wide stress triaxiality history is essential to accurately predict the deformation and rupture behaviors of the processes. In this study, a modified Lemaitre damage criterion which couples with the anisotropic Barlat 89 yield function is established. The effects of stress triaxiality, Lode parameter and shear stress on damage accumulation are considered in the constitutive model. The model is numerically implemented and applied to fracture prediction in tensile tests with different stress triaxialities and a complex deformation process with wide stress triaxiality history. The good consistency of predictions and experiments indicates that the modified Lemaitre damage model has excellent fracture prediction ability. Finally, the accuracy of the model is analyzed and discussed.     

Advances and trends in plastic forming technologies for welded tubes

With the implementation of environmental protection, sustainable development and conservation-oriented policies, components and parts of thin-walled welded tubes have gained increasing application in the aircraft and automotive industries because of their advantages: easily achieving forming and manufacturing process at low cost and in a short time. The current research on welded tube plastic forming is mainly concentrated on tube internal high-pressure forming, tube bending forming, and tube spinning forming. The focuses are on the material properties and characterization of welded tubes, finite element modeling for welded tube forming, and inhomogeneous deformation behavior and the mechanism and rules of deformation coordination in welded tube plastic forming. This paper summarizes the research progress in welded tube plastic forming from these aspects. Finally, with a focus on the urgent demand of the aviation, aerospace and automotive industries for high-strength and light-weight tubes, this paper discusses the development trends and challenges in the theory and technology of welded tube plastic forming in the future. Among them,laser tailor-welded technology will find application in the manufacture of high-strength steel tubes.Tube-end forming technology, such as tube flaring and flanging technology, will expand its application in welded tubes. Therefore, future studies will focus on the FE modeling regarding how to consider effects of welding on residual stresses, welding distortions and microstructure, the inhomogeneous deformation and coordination mechanism of the plastic forming process of tailor-welded tubes, and some end-forming processes of welded tubes, and more comprehensive research on the forming mechanism and limit of welded tubes.
