In this paper, a simple and efficient element is proposed for the free vibration buckling analysis of FGM beams. This formulating, based on Timoshenko beam theory. The assumption constant shear strain in reduces number unknowns addition to improving efficiency new element. performance evaluated with help several benchmark tests. First, accuracy convergence rate response are investigated separat...

since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...

This study investigated bending, buckling, and free vibration responses of hyperbolic shear deformable functionally graded (FG) higher order beams. The material properties of FG beams are varied through thickness according to power law distribution; here, the FG beam was made of aluminium/alumina, and the hyperbolic shear deformation theory was used to evaluate the effect of shear deformation i...

A parallel leaf spring guidance is defined as a benchmark problem for flexible multibody formalisms and codes. The mechanism is loaded by forces and an additional moment or misalignment. Buckling loads, changes in compliance and frequencies, and large-amplitude vibrations are calculated. A previously developed beam element for modelling the leaf springs is shown to be able to describe these phe...

Thin plate structures are more widely used in many engineering applications as one of the structural members. Generally, buckling strength of thin shell structures is the ultimate load carrying capacity of these structures. The presence of cracks in a thin shell structure can considerably affect its load carrying capacity. Hence, in this work, static buckling strength of a thin square plate wit...

Owing to their remarkable mechanical properties, carbon nanotubes have been employed in many diverse areas of applications. However, similar to any of the many man-made materials used today, carbon nanotubes (CNTs) are also susceptible to various kinds of defects. Understanding the effect of defects on the mechanical properties and behavior of CNTs is essential in the design of nanotube-based d...
