TL;DR: In this paper, a Bernoulli-Euler flexomagnetic (FM) nanobeam model is presented to investigate the influence of direct and converse couplings over the magnetic elastic response.
Abstract: The present paper presents a Bernoulli–Euler flexomagnetic (FM) nanobeam model, which considers the effects of flexomagneticity, piezomagneticity, and the surface elasticity. Differential control equations and corresponding magnetic boundary conditions are derived to investigate the influences of direct and converse FM couplings over the magnetic-elastic response. Size-dependent theoretical solutions for the static bending deformation of the cantilever, simply supported, and clamped nanobeams subjected to concentrated or uniformly distributed load are derived. Numerical simulations demonstrate that the flexomagneticity effect plays the role of the scale-dependent enhancement of the bending rigidity, which is independent of boundary conditions. But for the residual surface stresses, softening or stiffening the beam depends on boundary conditions.

TL;DR: In this article, three kinds of sandwich beams were prepared, which were cross, double cross and square sandwich structure (CSS, DCSS and SSS), using spruce wood as face panels, KH-560 modified jute fabrics reinforced epoxy laminated composites (JFRELC) as cores.

TL;DR: In this article, the effect of matrix reinforcement on the performance of heavily filled polyester resin composites is also presented, and it is envisaged that these filler ratios can by further increased without a loss of flexural strength.

TL;DR: In this article, the task of designing symmetric laminated beams with optimal stiffness and damping is considered by incorporating the damping model of Adams et al. into an optimization algorithm.
Abstract: The task of designing symmetric laminated beams with optimal stiffness and damping is considered by incorporating the damping model of Adams, et al. into an optimization algorithm. The design variables are the fiber orientation in each ply, the stacking se quence, and also the thickness of each ply in the laminate. A recursive quadratic program ming algorithm is employed for the optimization process and numerical results are presented for several test problems including the constraint condition of invariable flexural rigidity.
