The Bubnov-Galerkin’s method combined with the loading parameter method are applied in solving the mentioned problem. The influence of the hardening characteristics of material on the critical load is investigated.}, number={2}, journal={Vietnam Journal of Mechanics}, author={Bich, Dao Huy and Bay, Vu Khac}, year={2006}, month={Aug.}, pages={111–119} }
