Erratum for “Cylindrical Shells Under Ring Loads”

Computer aided reliability based design of ring-stiffened cylindrical shells under external pressure

A Level I code format is proposed for the buckling design of ring-stiffened cylindrical shells under external pressure. Depth independent partial safety factors to be applied to the resistance (collapse pressures), are proposed for the four relevant collapse modes Unterframe Shell Collapse, Frame Yield, Plate Yield and Frame Tripping), covering design and fabrication factors. A partial safety f...

Improved Smeared and Zigzag Third-order Theories for Piezoelectric Angle-ply Laminated Cylindrical Shells under Electrothermomechanical Loads

Elastic Buckling Analysis of Ring and Stringer-stiffened Cylindrical Shells under General Pressure and Axial Compression via the Ritz Method

Elastic stability of ring and stringer-stiffened cylindrical shells under axial, internal and external pressures is studied using Ritz method. The stiffeners are rings, stringers and their different arrangements at the inner and outer surfaces of the shell. Critical buckling loads are obtained using Ritz method. It has been found that the cylindrical shells with outside rings are more stable th...

Vibration analysis of FGM cylindrical shells under various boundary conditions

In this paper, a unified analytical approach is proposed to investigate vibrational behavior of functionally graded shells. Theoretical formulation is established based on Sanders’ thin shell theory. The modal forms are assumed to have the axial dependency in the form of Fourier series whose derivatives are legitimized using Stokes transformation. Material properties are assumed to be graded in...

Nonlinear Bulging Factors for Longitudinal and Circumferential Cracks in Cylindrical Shells Subjected to Combined Loads

Results of a geometrically nonlinear finite element parametric study to determine curvature correction factors or “bulging factors” that account for increased crack-tip stresses due to curvature for longitudinal and circumferential cracks in unstiffened cylindrical shells subjected to combined loads are presented. Nondimensional parameters varied in the study include the shell curvature paramet...
