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...
