Abstract
In this paper, the plastic limit load of cylindrical shells with opening subject to combined bending moment and axial force are found by finite element method using ANSYS suite of program. The effect of various parameters such as the geometrical ratios of shell and the shape, size, axial and angular position of the opening on the limit load of cylindrical shells under various loading conditions are studied. The plastic limit loads of cylindrical shells with circular openings of different opening ratios and combinations of dimensionless bending moment and axial force are calculated by finite element elastic-plastic method and their interaction curves are presented.
