On Critical Buckling Loads of Columns under End Load Dependent on Direction. [PDF]
Int Sch Res Notices, 2014 Most of the phenomena of various fields of applied sciences are nonlinear problems. Recently, various types of analytical approximate solution techniques were introduced and successfully applied to the nonlinear differential equations. One of the aforementioned techniques is the Homotopy analysis method (HAM).

Lifting, Loading, and Buckling in Conical Shells
Physical Review Letters, 2023 Liquid crystal elastomer films that morph into cones are strikingly capable lifters. Thus motivated, we combine theory, numerics, and experiments to reexamine the load-bearing capacity of conical shells. We show that a cone squashed between frictionless surfaces buckles at a smaller load, even in scaling, than the classical Seide/Koiter result.

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