- Abstract
- By using the ANSYS package, analyzed the influence of the aspect ratio of the rectangular cross-section of the spiral and annular ribs, with its constant area, on the stability coefficient of an isogrid lattice cylindrical shell of carbon-epoxy composite, loaded with longitudinal compressive and shear forces at the upper end. The results can be used in the design of similar structures.
