Numerical Modeling and Analysis of Composite Beam Structures Subjected to Torsional Loading
… equivalent homogeneous material, the effective torsional rigidity of the laminated composite rods can be determined by employing the theory developed by Lekhnitskii in 1963. Finally, the predicted results based on the present analytical approach are compared with those by the finite element, the …

Combined mechanical loading of composite tubes
… composite tubes subjected to combined axial and torsional loading. An elasticity based analytical model was developed to predict stresses and deformations in composite tubes subjected to combined thermomechanical loading. Material nonlinearities were modeled using the Endochronic Theory. The …

Design and In Vitro Evaluation of Five Epiphyseal Plate Fracture Stabilization Methods in Canines
… cranio-caudal bending, medio-lateral bending and torsional loading tests as well as destructive cranio-caudal bending and torsional loading failure tests. The study showed no statistically significant differences among the constructs for the destructive tests, suggesting the models failed prior to …

The torsional analysis of beams of arbitrary cross-section with non-linear stress-strain properties
… the torque-rotation relation, and the torsional capacity for prismatic beams with arbitrary cross-sections subjected to pure torsional loading. The technique may be applied to any beam with isotropic, homogeneous, linear or non-linear elastic properties and a known shearing …

Fatigue optimization of an induction hardened shaft under combined loading
… steel shaft subjected to combined bending and torsional loading. Finite element analysis is used first to develop unit-load factors for generating stress-time histories, and then, employing thermo-elastic techniques, to determine the residual stresses resulting from induction hardening. These …

A Biomechanical Analysis of One-Third Tubular Plates for the Treatment of Benign Lesions in the Distal Femur
… a 15 mm cortical defect under isolated axial and torsional loads. Second, an experimental combined axial/torsional fatigue analysis was employed to further analyze the behavior of the defect specimens, and to determine the structural stiffness regained by the addition of a one-third tubular plate. …

Solutions of some elastodynamic problems with application to crack propagation
… of an expanding penny-shaped crack under torsional loading. The problem of sudden arrest of a crack is treated by the method of self-similar potentials with the aid of appropriate time delays and origin shifts and by using a scheme of weighted superposition of fundamental problems. The …

Seismic behavior of circular reinforced concrete bridge columns under combined loading including torsion
… and column heights can be subjected to combined loading including axial, flexure, shear, and torsion loads during earthquakes. The combination of axial loads, shear force, and flexural and torsional moments can result in complex failure modes of RC bridge columns. This study carried out …

The theory of anisotropic thin- and thick-walled closed cross-section beams with coupled elastic deformations
… and of the beam walls, are taken into account. Torsional warping, both free and constrained as well as both primary and secondary, was also considered. An efficient method to account for 3-D elastic effects was developed by incorporating refined stiffness coefficients. All these effects play …

Analytical and Experimental Investigation of Low-Cycle Fatigue Fracture in Structural Steel
… subjected to different combinations of axial and torsional loading. The loading protocols and notch geometry were designed to produce different stress states at the location of fracture initiation. Finite element analyses were conducted to obtain the stress state and inelastic strains at the …

Implementation of an anisotropic plasticity model and its application to pile foundations problems
… the response under combined horizontal and torsional loading has received considerably less attention. The emphasis of this research is on using numerical simulation to investigate the response of pile foundations in soft clay under different loading conditions. The procedure is based on …

Analysis and optimal design of pressurized, imperfect, anisotropic ring-stiffened cylinders
… resistance as the relative magnitude of the torsional loading to axial compression loading is increased, but that this ring effectiveness decreases somewhat when internal pressure is added./p> The enforcement of stability constraints is treated in a way that does not require any eigenvalue …

Impact of complex system behavior on seismic assessment of RC bridges
… curved geometry subjected to multi-directional loading is non-trivial. The effect of the resulting combined interactions on structural response and its implications on system-level bridge vulnerability are assessed in this study. Fragility curves generated for bridges with varying parameters …
