Abstract: Finite element methods allow us to better understand the complex plastic deformation behaviour of a sheet metal component during forming. The purpose of the present work is to optimise the current 1535 × 1600 × 1.2 mm blank sheet of a commercial vehicle engine tunnel bottom using finite element simulation without violating safety and efficiency. The goal of this communication is to look at methods of finite element simulation that are used to solve the related problem. For generating the CAD data of the forming tools, a reverse engineering technique has been adopted. The formation simulation is performed using the commercially available PAMSTAMP explicit solver-based program. The blank holder force was increased by around 15 % (from the current force of 350 kN to 400 kN) while measuring the reduced blank width. The optimised blank sheet's simulation results have been compared to the current blank, ensuring that the optimised blank is appropriate for the bottom portion of the engine tunnel without any defects or failures being produced. In the application of sheet metal formation, finite element techniques have always enabled us in weight savings and cost-saving of automotive components.
