The degradation of the overall stability corroded rolled H-shaped steel beams under bending conditions has not been extensively studied. In present study, monotonic tensile tests and were conducted on seven that subjected to electrochemical corrosion in order discuss influence material’s mechanical properties conditions. test results have indicated strength, elastic modulus, elongation declined...

Free vibration analysis of prestressed, homogenous, Fiber-Metal Laminated (FML) and composite beams subjected to axial force end moment is revisited. Finite Element Method (FEM) frequency-dependent Dynamic (DFE) models are developed presented. The frequency results compared with those obtained from the conventional FEM (ANSYS, Canonsburg, PA, USA) as well Homogenization (HM). Unlike FEM, applic...

We report the axial strain dependence of two types of all-fiber acousto-optic tunable filters based on flexural and torsional acoustic waves. Experimental observation of the resonant wavelength shift under applied axial strain could be explained by theoretical consideration of the combination of acoustic and optical effects. We discuss the possibility of suppressing the strain effect in the fil...

If patient-specific finite element models of the spine could be developed, they would offer enormous opportunities in the diagnosis and management of back problems. Several generic models have been developed in the past, but there has been very little detailed examination of the sensitivity of these models' characteristics to the input parameters. This relationship must be thoroughly understood...

In cylindrical shells, the lowest natural frequency is not necessarily associated with the lowest wave index. In fact, the natural frequencies do not fall in ascending order of the wave index either. Solution of the vibration problem of cylindrical shells also indicates repeated natural frequencies. These modes are referred to as double peak frequencies. Mode shapes associated with each one of ...

Due to the commonly eccentric connection on only one angle leg (bolted or welded), additional bending moments are acting member under compression axial force, leading a complex load-carrying behaviour with flexural and/or torsional buckling phenomena. Furthermore, type and size of rotational restraints at member's ends (provided by adjacent structure) significantly influence capacity these memb...

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...
