Material properties of the beam change in the thickness direction according to power-law distributions with different porosity models. It is known that post-buckling problems are geometrically nonlinear problems. In the nonlinear kinematic model of the beam, total Lagrangian finite element model of two dimensional (2-D) continuum is used in conjunction with the Newton-Raphson method. In the study, the effects of material distribution, porosity parameters, compression loads on the post-buckling behavior of FG beams are investigated and discussed with porosity effects. Also, the effects of the different porosity models on the FG beams are investigated in post-buckling case.eninfo:eu-repo/semantics/closedAccesspost-bucklingfunctionally graded materialporositytotal Lagragianfinite element methodArticle10.12989/scs.2017.24.5.579245579589WOS:000407584200006Q1Q1
