Aircraft structures are made of thin-walled as it provides higher stiffness to weight ratio compared solid sections, but is prone buckling due its low and slenderness the individual element. One types that can impact integrity a beam lateral torsional which caused by simultaneous bending twisting cross-sections happens before beam's material strength reached. Therefore, design such structure sh...

In this research, the numerical and experimental analysis of the carbon fiber composite lattice conical structure has been performed to assess the buckling stability of the structure before and after the lateral impact. In the experimental analysis, the carbon fiber composite lattice conical structure was constructed with the winding method and using elastic molds and metal mandrel. In or...

Torsional dynamic analysis of carbon nanotubes under the effect of longitudinal magnetic field is carried out in the present study. Torque effect of an axial magnetic field on a carbon nanotube has been defined using Maxwell’s relation. Nonlocal governing equation and boundary conditions for carbon nanotubes are obtained by using Hamilton’s minimum energy principle. Eringen’s nonlocal stress gr...

C and Z sections are two of the most common cold-formed steel shapes in use today. Accurate prediction of the bending performance of these sections is important for reliable and efficient cold-formed steel structures. Recent analytical work has highlighted discontinuities and inconsistencies in the American Iron and Steel Institute ~AISI! and Canadian Standards Association ~S136! design provisi...

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...

Parallels are drawn between the response of a discrete strut on a linear elastic foundation and force-chain buckling in a constrained granular medium. Both systems buckle initially into periodic shapes, with wavelengths that depend on relative resistances to lateral displacement, and curvature in the buckled shape. Under increasing end shortening, the classical structural model evolves to a loc...
