Simulation Of Thermal Buckling Of Delamination By Fiber Bridges

This paper reviews the history and current status of buckling researchand discusses the calculation means for thermal buckling. For rectangularplates buckling under thermal load, the paper uses ANSYS to simulate thethermal buckling of delamination because of the limitations of analyticalsolutions,.This article has five chapters:The first chapter recalls the background buckling research anddiscusses the importance of these works and introduces the specificcontent of the research. The second chapter describes the basic conceptof buckling, the theory of thermal buckling and the characteristics ofnonlinear buckling. The second paragraph discusses the basic concepts ofbuckling, thermal buckling analysis of theoretical compulations andnumerical simulation principle.Chapter III uses finite element software ANSYS for thermal bucklingof thin rectangular plate in uniform and non-uniform temperaturefield.This chapter considers various aspect factors, such as the relativethickness of the rectangular plate, in the role of different fiber bridgestiffness. The results show that binding effect of the fiber bridge caneffectively improve the ability to resist thermal buckling of delaminationand buckling can greatly inhibit the expansion.Chapter IV explores the finite element software ANSYS to simulateconstrained buckling of delamination under different load cases. From thesimulation results we can see, fiber bridges can improve the criticalbuckling load and improve the carrying capacity of structures. The critical load of buckling under mechanical and thermal loads is greatly enhancedas the increase of fiber bridge stiffness. The greater the fiber bridgestiffness, the smaller the buckling region.The last chapter lists the main conclusions and deficiencies to lookforward to further research.
