ON THE INFLUENCE OF FLEXURAL RIGIDITY AND WIRE LENGTH ON POWER LINE DEFORMATION

Numerical studies of the deformation dynamics of a high-voltage transmission line conductor were based on the hypothesis of a perfectly flexible model, taking into account compressive and tensile forces. Of practical inter est is the effect of the conductor's bending stiffness on its deformation state depending on the...

IMPACT OF PRESSURE ON THE DEFORMATION OF BLATZ-KO CYLINDRICAL MATERIAL

This paper examines the finite deformation of hollow cylinders made from compressible Blatz-Ko hyperelastic material under internal, external, and combined pressure loading. It derives parametric closedform solutions for radial displacement and stress using the Cauchy stress tensor and equilibrium equations. Materials...

Improved Method for the Design of Intermediate Transverse Stiffeners in Steel Plate Girders

Steel plate girders benefit from transverse stiffeners, which reduce the web length along the span and enhance shear resistance. They also mitigate web buckling by providing lateral support to the web and anchoring the axial compression induced by the tension field action. According to EN 1993‐1‐5:2024, the design of t...

The strain-energy function for combined bending and stretching of incompressible isotropic elastic plates

The strain-energy function of a thin plate composed of an incompressible isotropic elastic material is derived. In contrast to conventional models developed for applications involving large plate deformations with small midplane strains, the present model accommodates large deformations accompanied by finite midplane s...

Axial–Torsional Path Dependence in an Elastoplastic Rod with a Multiply Connected Cross-Section

This paper addresses the elastoplastic torsion and tension of a prismatic bar with a multiply connected circular cross-section containing one central and four symmetrically arranged lateral holes. The relevance of this problem stems from the fact that internal contours alter the shear-stress flow, amplify local gradien...
