Abstract

This paper introduces a shear deformable numerical model for conducting nonlinear stability analysis of beam-type structures. The incremental equilibrium equations for a straight thin-walled beam element are derived using the updated Lagrangian formulation, taking into account the nonlinear displacement field of cross-sections. This formulation considers both restrained warping and large rotation effects. Shear deformation effects are incorporated into the composite cross-section by considering the coupling effects of bending-bending and bending-warping torsion. The crosssection properties are calculated based on the reference modulus, allowing for the modeling of different laminate configurations. A numerical algorithm is developed to calculate the geometric properties of the composite cross-section. Various material configurations are examined, and several benchmark examples are presented for verification purposes. The obtained results demonstrate that the proposed model is free from shear locking issues and performs reliably.
