Our portfolio with some general information about analyses that were carried out.
Crash cushion - EuroTRACC
The aim was to analyze impact severity on occupants according to EN1317.
Validation of our numerical models of vehicles and the barrier terminal was performed. After successfull validation we conducted simulations under all impact conditions for certification specified in EN1317. The simulations were of an explicit time integration scheme with highly nonlinear material parameters and boundary conditions using finite element method.
Exemplary results are presented below.

Crash cushion - SafeEnd
The aim was to analyze the safety of the system in the application on the roads.
Multiple numerical simulations of car crashes under various impact conditions were carried out using initially validated numerical models. The simulations were of an explicit time integration scheme with highly nonlinear material parameters and boundary conditions using finite element method.
Exemplary results are presented below.

Road Safety Barrier - concrete
The aim was to analyze impact severity on occupants according to EN1317.
We built and validated our numerical model of concrete road safety barrier. Then, we carried out multiple numerical sumulations under various impact conditions. The simulations were of an explicit time integration scheme with highly nonlinear material parameters and boundary conditions using finite element method.
Exemplary results are presented below.
