The stability against a synchronous sinusoidal disturbance of any wave length is investigated and the analytic expression of the buckling amplitude is derived in the weakly non-linear regime by considering both geometric and material (hyper-elastic) non-linearities. The bifurcation is super-critical in the long wave length domain for any elastic constitutive law, and sub-critical in the short wave length limit for a limited range of non-linear material parameters. %G English %2 https://hal.science/hal-02733481/document %2 https://hal.science/hal-02733481/file/Art_Mora_Nonlinear_Dyn._2020.pdf %L hal-02733481 %U https://hal.science/hal-02733481 %~ CNRS %~ LMGC %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
