The objective of the current work is to estimate the maximum resultant displacement and energy absorption capacity of fascia and body in white structure during crash. Any change in automobile design leads to decrement of passenger's compartment area. Therefore, another option available is to change the materials in automobile which can minimize the damages in accidents. The details of the Fascia and body in white structure are taken from Honda Accord Model. The crash tests are performed on fascia considering the Dual Phase 600 Steel, TI6AL4V alloy and Acrylonitrile Butadiene Styrene (ABS) Plastic materials. The fascia crash test is performed as per United States New Car Assessment Program and Roof crush test is performed as per federal motor vehicle standards 216. Deformation and energy absorption capacity during crash have been analyzed by using finite element solver LS-DYNA. The results shows that, the energy absorption capacity of Dual Phase 600 Steel is greater than that of TI6AL4V alloy and Acrylonitrile Butadiene Styrene (ABS) Plastic during the fascia crash test. In case of roof crush test, maximum resultant displacement of Dual Phase 600 steel is less compared to TI6AL4V Alloy. This analysis helps in selection of material which can minimizes the damage during vehicle accidents. [ABSTRACT FROM AUTHOR]
