Post-Buckling of Piezoelectric Thin Plates

International Journal of Structural Stability and Dynamics, 2015
In the present paper, the geometrically nonlinear behavior of piezoelastic thin plates is studied. First, the governing equations for the electromechanically coupled problem are derived based on the von Karman–Tsien kinematic assumption. Here, the Berger approximation is extended to the coupled piezoelastic problem.

Local and post-buckling behavior of corroded axially-compressed steel columns

, 2020
To investigate the effect of corrosion on the local and post-buckling behavior of axially-compressed steel members, H-shaped Q345B steel columns with different corrosion degrees were obtained by accelerated corrosion test. Then, an axial compression test

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.
