In the present paper, employing a complete model of a passenger car, contribution of various components and assemblies in the frontal crash energy absorption is determined. Thickness of components with more remarkable contribution is increased to improve the occupant safety. Furthermore, effects of substituting the metallic bumper with one fabricated from GMT materials on the frontal crash beha...

This paper focusses on recent developments and on-going research related to parallel and distributed approaches for crashworthiness simulation, using the PAM-CRASH code from ESI as an example. The developments described here relate directly to the take-up in the automotive industry of the latest High Performance Computing (HPC) technology, since crash and safety analysis is well established in ...

This paper addresses parallel programming paradigms for nonlinear, explicit finite element simulations primarily employed for crashworthiness and occupant safety simulations in the automotive industry. The reliance of industrial design on computer simulation and state-of-the-art high performance computing architectures will be discussed as a motivation for the need for parallel implementations ...

A finite element methodology has been developed for predicting the behaviour of honeycomb structures. Dynamic analysis of hexagonal aluminium honeycomb structures is carried out using PAM-CRASH, an explicit FE analysis code, and the result are verified against experimental data. Relationship between the crushing behaviour of honeycomb and simulation parameters has been established. The simulati...

Automotive manufacturers rely on rigorous testing and simulations to construct their vehicles durable safe in all aspects. One such vital factor is crash safety, otherwise known as crashworthiness. Crash tests are conventional forms of non-destructive methods validate the vehicle for its crashworthiness compatibility based different operating conditions. The frontal impact test most primary for...

Safety of the occupant during the crash is very essential design element. Many researches have been investigated in reducing the fatal injury of occupant. They are focusing on the development of a dummy in order to obtain the real human like motion[1]. However, they have not considered the arm resist motion during the car accident. In this study, we would like to suggest the importance of the r...

Load imbalance is the most important factor that limits scalability of parallel applications in scientific computing. Dynamic load balancing at the application level usually is implemented in a proprietary manner. This paper presents a generic framework for application level dynamic load balancing. Our framework can be applied to any grid-based iterative numerical simulation. It defines a progr...
