The subject of the study is one orthotropic thin-walled sandwich beam with trapezoidal core and two-layer facings. The outer layers of facings are flat, but inner layers are trapezoidal corrugated. The main core of the beam is also trapezoidal corrugated – in perpendicular direction to the corrugation of inner layers of facings. The beam is with lengthwise corrugated layers and crosswise corrugated main core. The mathematical and physical model of this beam is formulated, and also the field of displacements. The system of equilibrium equations is analytically derived using the energy method. The obtained solutions will be verified numerically (FEM)
