The deformability of a rope anti-ram barrier when a car hits: part 1. Problem statement

For the purpose of digital testing of a rope anti-ram barrier, interrelated models of the deformability of its power cables and an oncoming truck have been formulated. The models take into account the competition between the destruction of barrier structures and the car. Thus, due to the unclosed nature of the cables (the presence of free ends), the first model evaluates the etching of the cables and the irreversible relaxation of the cable loops. The second model evaluates the inelastic impact of the truck on the power cables and the deformation of its front suspension. The anti-ram barrier will withstand digital tests if it collapses later than the car.
