Programming Crashworthiness Simulation for Parallel Platforms
نویسندگان
چکیده
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 of such codes. Concrete descriptions of parallelisation strategies using shared-memory micro-tasking, message-passing, and high performance Fortran will be given for the industrial simulation code PAM-CRASHTM (and the related code PAM-SAFET” ), together with performance results on a variety of parallel platforms. @ 2000 Elsevier Science Ltd.

متن کاملOptimization foam filled thin-walled structures for the crashworthiness capability: Review
In automotive industry, foam-filled structures have aroused increasing interest because of lightweight and capacity of energy absorption. Two types of foam filled thin walled structures such as the uniform foam filled (UF) and the functionally graded foam (FGF). To improve crashworthiness performance, FGF are used to fill structures, unlike existing uniform foam materials. In addition, by seeki...
