This paper presents the surface piezomagnetoelasticity theory for size-dependent buckling analysis of an embedded piezoelectric/magnetostrictive nanobeam (PMNB). It is assumed that the subjected forces from the surrounding medium contain both normal and shear components. Therefore, the surrounded elastic foundation is modeled by Pasternak foundation. The nonlocal piezomagnetoelasticity theory i...

We have solved the governing equations for the buckling of rectangular functionally graded plates which one of its edges has small non-zero deflection and moment. For the case that the material properties obey a power law in the thickness direction, an analytical solution is obtained using the perturbation series. The applied in-plane load is assumed to be perpendicular to the edge which has no...

Analytical solutions for elastic buckling and post-buckling geometries are scarce. The present work presents such a solution sample geometry, initially planar, which buckles into complex 3D shape under tensile load. assumptions that the thickness is small, so flexural stiffness low compared to in-plane strain stiffness, hence can be considered inextensible. initial geometry composed of two disk...

Structural buckling failure due to high external hydrostatic pressure is a major consideration in designing rings and long cylindrical shell-type structures. This paper presents a direct approach for enhancing buckling stability limits of thin-walled rings/long cylinders that are fabricated from multiangle fibrous laminated composite lay-ups. The mathematical formulation employs the classical l...

In this study buckling analysis of solid rectangular plate made of porous material in undrained condition is investigated. The mechanical properties of plate are assumed to vary through the thickness direction. Distributing of the pores through the plate thickness are assumed to be the nonlinear nonsymmetric, nonlinear symmetric, and monotonous distribution. The effect of pores and pores distri...

Stainless steel square-honeycombs have been manufactured by slotting together steel sheets and then brazing the assembly. Their out-of-plane compressive response has been measured as a function of the relative density, the ratio of specimen height to cell size, and the degree of constraint associated with bonding of the honeycomb to face-sheets. It has been found that, for the practical range o...

We examine the force needed to extend/compress a bio-filament, a key issue in the study of cytoskeleton mechanics and polymer physics, by considering both the associated stretching and bending deformations. Specifically, closed form relationships are derived to predict the buckling of stiff filaments such as F-actin and microtubules. Our results clearly demonstrate that the maximum force a 2D f...

Daily-life foldable items, such as popup tents, the curved origami sculptures exhibited in the Museum of Modern Art of New York, overstrained bicycle wheels, released bilayered microrings and strained cyclic macromolecules, are made of rings buckled or folded in tridimensional saddle shapes. Surprisingly, despite their popularity and their technological and artistic importance, the design of su...

Adhesive joints find numerous applications in various industrial fields. They represent a valid alternative to traditional joining methods. Much of the available scientific literature has focused on study adhesive subjected tensile loads. There have also been studies concerning stresses distributions layer. However, real case applications, could be subject cyclic tensile-compression loads and t...
