Numerical simulations of local and global buckling of hyperelastic tubes with different cross-sections
Łukasz Kowalewski , Stanisław Jemioło
AbstractThe aim of the article is to present the application of finite element method (FEM) programs ABAQUS/Standard  and ABAQUS/Explicit  and the constitutive models of incompressible isotropic hyperelastic materials  in the analysis of local and global buckling of axially compressed shell elements made of elastomers. Three FEM models of tubes with the same length and initial stiffness have been created for this urpose. These are tubes with elliptical, square and triangular cross -sections. Three types of consti tutive models of a rubber-like (elastomeric) material are used - with the polynomial function of elastic energy in the form of the model MV  and standard models of Neo-Hooke and Mooney-Rivlin . No imperfections are introduced in the FEM models of the analyzed pipes. Numerical simulations of buckling of pipes are performed for two types of inital-boundary value problems, i.e. quasi-static and dynamic ones. It has been shown that the type of buckling depends on the cross-section of the pipe. The solutions of buckling of pipes modelling with different constitutive models are compared and good correlations of the results have been observed .
