Sažetak
A free shear-locking beam model for numerical stability analysis of composite beam-type structures is presented. The incremental equilibrium equations for a straight fourteen- degree-of-freedom beam element are derived within the framework of updated Lagrangian formulation. In this, the nonlinear displacement field of a thin-walled cross-sections, accounting for the restrained warping and the large rotations effects, is applied. The applied shear-deformable beam formulation accounts for the flexural- torsional coupling appearing when a non-symmetric cross-section is considered. Cross-section properties are calculated using the reference modulus, which enables to model various cross-ply cross-sectional wall configurations. The numerical algorithm is implemented in a computer program and validated through several benchmark examples.
