A generalized approach was developed for solving plane and spatial contact problems in a dynamic elastic-plastic formulation. The spatial problem of a strain stress state of a beam made from the composite reinforced two-layer material is being solved. The reinforced or armed composite material consists of two materials: the main material of glass and the reinforcing thin steel layer. Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical and technological use in the modern industry. Glass has high strength and is not affected by the processes of aging of the material, corrosion, and creep. In addition, this material is cheap and widely available. The reinforced composite beam is rigidly linked to an absolutely solid base and on which an absolutely solid impactor acts from above in the centre on a small size of the area of initial contact.
