Stress Analysis of Post-Buckled Sandwich Panels

Volume 3: Structures, Safety, and Reliability, 2018
The paper presents a method to assess stresses in sandwich plates with periodic microstructure in the post-buckling region. The fundamental assumption is that the microstructure is linear elastic and von Karman non-linearity is present only at macro-, i.e. panel-scale.

PERTURBATION APPROACH TO ELASTIC POST-BUCKLING ANALYSIS

Computers & Structures, 1998
Summary: This paper shows that effective and reliable computer codes can be obtained by a suitable finite element implementation of the Koiter's perturbation method. However, careful attention has to be paid to all the implementation details in order to avoid kinematic inconsistencies that can strongly affect the results.

Finite element post‐buckling analysis for frames

International Journal for Numerical Methods in Engineering, 1977
AbstractPresented in this paper is a direct method of analysis of the elastic non‐linear behaviour of frames. Emphasis is given to the method's capability of tracing the post‐buckling path from a bifurcation point although the method can also trace the non‐linear behaviour of frames with eccentricities.

Post-Buckling Analysis of Guyed Towers

Journal of the Structural Division, 1981
The post-buckling behavior of short towers, supported by a single set of guy wires is investigated. Using the principle of stationary potential energy, a set of non-linear algebraic equations are obtained for both fixed and hinged-base towers. The equations are solved numerically for several actual systems.

Post-Buckling Analysis of Cylindrical Shells

Journal of the Engineering Mechanics Division, 1978
A method is presented for the calculation of the critical load and post-buckling displacements of elastic structures, and is demonstrated on circular cylindrical shells. The critical load is found by successive extrapolations of the load with the aid of the tangent stiffness matrix determinant.

Post-buckling analysis of laminated stiffeners

Computers & Structures, 1993
Summary: An analytical-numerical procedure is extended to investigate the local buckling and post-buckling behaviour of thin-walled laminated stiffeners under uniaxial compression. Two stiffener sections are considered: \(I\)- section and channel section. The stiffener section is treated as a plate assembly.
