In this work we present a new concept for friction damping which is based on the permanent magnetization and flexibility of magnetoactive elastomers (MAE). The called “magnetofriction” studied sandwich structure in work. assembled consists MAE core ferromagnetic skins. Due to MAE, skins are attracted without need glue or other means fixation. magnetic forces generate normal loading contact inte...

The article focuses on the structural performance of sandwich beams with hollow truss lattice cores made from a ductile stainless steel. The trusses are arranged in an orthogonal (cross-ply) configuration, in either ±45 (diamond) or 0 /90 (square) orientations with respect to the face sheets. The responses in shear, tension and compression, as well as simply supported and fully clamped bending,...

A multifunctional panel concept is presented in which a lightweight, structural sandwich panel is able to undergo a reversible change in shape upon application of a localized thermal stimulus. The shape change is effected by metallic (or polymeric) shape memory (SM) face sheet elements, which exploit a “one-way” SM effect only. Unlike other designs, no external or bias forces are required to co...

In this work, geometrically nonlinear static bending analysis of sandwich beams with a porous core and two skins made functionally graded materials using mesh-free method is presented. The material types the face sheets beam are chosen so that continuity between layers guaranteed. governing equation including geometric nonlinearity established via principle virtual work. This discretized into s...
