The derivation of the stresses in a pressurised pipe or cylindrical vessel with initial geometric imperfections

Strain, 1988
Several analytical methods are outlined to deal with the title problem when the vessel is free of external constraints. In essence these correspond to the Haigh equation, which provides a nonlinear relationship between the induced circumferential stress and the applied internal pressure.

Influence of Initial Geometric Imperfections on the Vibrations and Dynamic Stability of Elastic Shells

International Applied Mechanics, 2004
The results from studies into the vibrations and dynamic stability of thin elastic shells with initial geometric imperfections are analyzed. The corresponding dynamic problems are solved in both linear and nonlinear formulations. The influence of initial axisymmetric and nonaxisymmetric deflections on natural, forced, parametrically excited, and self ...

Influence of initial geometric imperfections on vibrations of thin circular cylindrical shells

Computers & Structures, 1983
Abstract The influence of initial geometric imperfections (out-of-roundness) on vibrations of a right circular cylindrical shell is investigated on the basis on non-linear large deformation shell theory. Both free and forced motions (due to base excitation caused by seismic effects) are treated.

Study on Buckling of an H-Shaped Steel Member with Initial Geometric Imperfection

Applied Mechanics and Materials, 2012
Based on Ježek method of computing the elastic-plastic buckling of the member under the axial compressive load and the bending moment, considering the initial imperfection, the analytical expressions of calculating the ultimate load of buckling about the neutral axis with the maximum moment of inertia for an H-shaped member are derived.

Geometrically Nonlinear Theory of Initially Imperfect Sandwich Curved Panels Incorporating Nonclassical Effects

AIAA Journal, 1997
Summary: A geometrically nonlinear theory of initially imperfect doubly curved sandwich shells is developed. The theory encompasses sandwich structures with dissimilar face sheets constructed of laminate composites and with the core modeled as an orthotropic body featuring strong or soft behaviors.
