Structural insulated panels are an alternative material for residential housing and lightweight industrial construction. These panels consist of a core made of high-density expanded polystyrene, surrounded by a wooden frame, and sandwiched between two outer layers of wooden oriented strand board (OSB). The OSB layers are bonded to the core using high-strength adhesives. This work presents the results of finite element simulations carried out to evaluate the behavior of a panel subjected to static tests involving eccentric vertical loads and four-point bending. The panel is modeled using linear hexahedral solid elements with a general-purpose code. Linear buckling analysis and geometrically nonlinear analysis are conducted, comparing the numerical results with experimental data for both loading configurations.
