In the last few decades, energy absorption of materials becomes an critical issue in a design process of a vehicle because risks of primary and secondary accidents against pedestrians, other road users and structures can be reduced by a performance of absorbing energy in its support structures. Among various materials used for the structures, TRIP steel with favorable mechanical properties such as excellent formability and higher impact energy absorption is attractive to automotive industries. Huge numbers of research works have been carried out to investigate deformation behavior of TRIP steel. However, just few studies can be found on the performance in TRIP steel, especially, at higher deformation rate during the crash of the vehicle. Kinetic energy by higher speed of the vehicle will be consumed by inelastic bending deformation of components. Thus, a consideration of bending deformation at high impact velocity is required for the evaluation of the performance. In this study, the performance in TRIP steel at high deformation rate is clarified by conducting both quasi-static and impact three-point bending tests for pre-cracked specimen.

The main motive of this research is to develop an energy absorber system for automobiles and perform an experimental disquisition by applying different parameters to check the effect of the crash on the machine’s front cushion by perfecting energy-absorbing capacity for the passenger safety aspect. Considering automobile vehicle speed limits similar to (Low, Medium, and High), the speed limits in India vary by state and vehicle type. In Karnataka, there is no limit (60 km/hr for buses in Bangalore except on Airport Road where it is 80 km/hr and 100 km/hr for buses only on NH and 66 km/hr between Mangalore and Udupi). Transport vehicles have a limit of 66 km/hr. This data is set with cooperation between the state and the ministry of highway department for light motor vehicles and buses. My exploration: considering the norms as per international safety regulations, and the purpose of an automobile's safety systems, the experimental set-up was designed so that a straight pendulum would strike the bumper system, and the front, and rear impacts would hit at 4.5 to 5 km/h, and the loaded or unloaded car would hit at 3 km/h and 46 cm above the front and back corners. To achieve this goal and to develop the energy absorber system, we used appropriate parameters such as CAD, CAM, CAE, testing, Simulink, and hand computation, enforcing the criteria in a unique development perspective by adding crash capability with a spring-loaded system, minimising crash effects, increasing immersion capacity, and implementing it on the SUV front cushion system.

“…Increased attention has been given to the development of new designs of energy-absorbing devices such as crush cans and bumper beams to improve their crashworthiness values and energy absorption capabilities. 2–13 There has been much research in the area of smart materials which may begin to find roles in future active applications. 14–16 A crumple zone, on the other hand, is designed to crumple and deform permanently in order to absorb energy when impact occurs.…”

Nowadays, most energy absorbing devices used in industry absorb energy through permanent deformation. In some cases, consumers have to repair or even replace energy absorbers even after a mild collision. The work presented in this paper proposes a novel re-usable solution in the form of a hybrid bumper-crush can design where a recoverable structure is integrated into the bumper beam and crush can for a mild collision situation in addition to the traditional energy absorbers recommended for more severe collisions. The main investigation is focused around the performance and optimisation of Negative Stiffness honeycomb, the recoverable structure and honeycomb-filled elements. A comprehensive study was undertaken to investigate numerically the behaviour of these energy absorbing structures under crash conditions, corresponding to real scenarios and simulated using a specially developed finite element model.
