It was shown that the magnitude of the vehicular impact force depends on four factors: mass, speed, crushing characteristics of the vehicle, and barrier stiffness. FLEX IMPACT® Traffic Barriers are a form of impact protection specifically designed to protect machines and buildings from collisions with forklifts or other heavy vehicles. Mr Tay said, “it behaves like a shock absorber”, adding that, “unlike conventional metal barriers, this system absorbs the (crash) impact and deflects it, making it safer for the driver and reduces the likelihood of a vehicle crashing through the barrier”. The destructive nature of vehicular crashes imposes significant challenges to barrier design using full-scale physical testing; numerical simulations thus become a viable option to support guardrail design improvements and performance evaluation.
