Buckling load optimization for 2D continuum models, with alternative formulation for buckling load estimation [PDF]

open access: yesStructural and Multidisciplinary Optimization, 2018
Buckling load estimation of continua modeled by finite element (FE) should be based on non-linear equilibrium. When such equilibrium is obtained by incremental solutions and when sensitivity analysis as well as iterative redesigns are included, the computational demands are large especially due to optimization.

Creep Buckling Under Varying Loads

open access: yesJournal of Pressure Vessel Technology, 1989
Creep buckling analyses under stepwise varying loads are performed on a circular cylindrical shell with initial imperfection subjected to axial compression and a partial spherical shell under uniform external pressure. The finite element method is applied to a creep deformation analysis to obtain the critical time when creep buckling occurs.
