WitrynaYou must request results (.fil) file output for the nodal displacements so that you can use the buckling analysis results to seed the ABAQUS/Explicit mesh with imperfections. In addition, request preselected field variable output to the output database (.odb) file and prevent unnecessary results from being printed in the data (.dat) file. Witrynaabaqus压杆屈曲分析
WitrynaAn imperfection in the form of the critical buckling mode (obtained in the previous analyses of the example) is assumed to be the most critical. The mesh is, therefore, perturbed in the radial direction by that eigenmode, scaled so that the largest perturbation is a fraction of the shell thickness. ... Abaqus will estimate the eigenvalues in ...
