| Abstract: | The 3D cyclic symmetric finite element model(FEM) is created and its vertical load case is simulated with such three methods as the linear static solution,the incremental and iterative nonlinear solution and the quasi-static solution by ABAQUS.The charateristics,techniques and results of the three solutions are discussed respectively and compared with each other at length.The advantages and disadvantages of each method are summarized,which aims to provide reference for the finite element analysis and the de... |
