Modeling of Neck Effect in Cylindrical Shell

Modeling of Neck Effect in Cylindrical Shell

Adam Piwowarczyk, Artur Ganczarski

Abstract. This work presents two models of a neck effect appearing in a cylindrical shell. In the first case, an elastic deformation is described by the conventional shell equation in which axial force appears as an external loading. In the second case, an elastic-plastic deformation including damage effect is described by the kinetic theory of damage evolution implemented to FEM code. Results obtained from both models confirm existence of a distinct displacement, stress and damage localization in the cylindrical shell free from any geometrical or material imperfections.
