Abstract
The work presents the numerical analysis of composite shell with geometric imperfections subjected to compression along its generatrix. The imperfections are described as single indentations and random fields with random parameters of shape and correlation. The fields are generated with the use of the authors made program. Using the authors’ FEM software as well as commercial package Femap with NX Nastran, the critical load values are obtained for the shell with different imperfections. A comparative analysis of the results is performed in terms of change in the loading capacity of the shell.
