This simulation is performed with Explicit approach.
This is similar to the crash box inside the car which is generally used to absorb energy by Buckling and folds in axial direction
A crash box is highly energy absorbing structure that crashes on application of load and reduces the impact on the other component nearby, also crash box is an important component in determining crashworthiness, and is placed between the bumper and side rails of automotive vehicle.
Crashworthiness is described as the ability of vehicular structure to absorb dynamic energy and minimize injury to the passenger during collision, and is consider among the most important criteria in determining vehicle design with regards to passenger safety.
Traditionally, aluminum and steel have been used for making crash boxes in cars. However, insistence on light weighting combined with high stiffness and strength has led to composite gaining preference for used in cars, as all these properties are crucial in achieving better crashworthiness.
The FE simulation helps engineers how component interacts in an assembly and how the failure mode and mechanism is developed during impact loading. The crash box used here is made up of steel material with initially elastic property and prolonged to have plastic non-linear effect.
