Abstract

Impact of Automotive GMT(Glassfiber reinforced Mat Thermoplastic) Bumper for '5Mhp Barrier Test'was simulated using ls-dyna. The FE model consists of foam which is energy absorber, bumper beam and stay etc. Bumper intrusion and deflection was compared with the experimental results. Effects of uncertainty of material property and deviation of impact velocity were considered and results were compared with those of base design. Effects of number of integration points through th thickness was also investigated.
