In this post, we are going to do a nonlinear buckling analysis for a thin arch shell under uniformly distributed pressure. The configuration of the arch shell is as follows During the analysis, a linear buckling analysis will be conducted first to obtain the 1st-order eigenvalue (i.e. the linear buckling load) and eigenmode (i.e. buckling … Continue reading Nonlinear buckling analysis: considering both large deformation and material nonlinearity
