The International Linear Collider (ILC) is being designed to explore particle physics at the TeV scale. The design of the Very Forward Region of the ILC detector is considered in the presented work. The Beam Calorimeter one of two electromagnetic calorimeters situated there is the subject of this thesis. The Beam Calorimeter has to provide a good hermeticity for high energy electrons, positrons...

Sandwich structures are widely used in many industrial applications and especially light aviation. The local buckling phenomenon named “wrinkling” is one of the primary causes compressive failure such structures. Its calculation a difficult practical problem since this cannot be captured by GFEM (Global Finite Element Model) classically for aircraft structure sizing. Therefore, pre-sizing invol...

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,...
