抄録

In order to study the method of the reduction of the weight of a plastic bottle, the buckling mode of plastic bottles under longitudinal compression is analyzed by finite element simulation. A parameter to evaluate the buckling deformation is proposed, and the buckling deformation is estimated through the comparison of load-deformation and the history of the parameter. The buckling deformation is classified into 5 types, the sinking of the neck type 1 and type 2 and the buckling of the shoulder, body, and base. A parameter γ, the rate of the equivalent plastic strain, and a parameter α, the rate of γ are defined. It is shown that for the buckling of the shoulder, body, and base, γ and α can be used to evaluate the buckling deformation by the same values for the buckling parts. For the sinking of the neck, γ and α can be used to evaluate the buckling deformation by changing the values for bottle shape and thickness. These parameters can specify the buckling point, which cannot be found by considering the load-deformation history.
