Abstrakt EN: Paper is focused on progressive failure analysis of sandwich composite beam loaded with transversely low-velocity impact. A user defined material model was used for modeling of the non-linear elastic behavior of composite skin of resulted sandwich structure. The non-linear behavior of foam core was modeled using Low-Density Foam material model. The results between numerical model and performed experiments were compared in form of deflection and contact force time dependencies and occurrence of damage too.
