Structural adaptivity for acceleration level reduction in passenger car frontal collisionsInternational Journal of Crashworthiness - Tập 9 - Trang 121-127 - 2004
L Wågström, R Thomson, B Pipkorn
A mathematical model was developed to explore and demonstrate the injury
reducing potential of an adaptable frontal stiffness system for full frontal
collisions. The model was validated by means of crash tests and was found to
predict the peak accelerations of the crash test vehicles well, whereas
correlation concerning mean acceleration or residual crush was not found.

Numerical modelling of the axial plastic collapse of externally grooved steel thinwalled tubesInternational Journal of Crashworthiness - Tập 8 - Trang 583-590 - 2003
A G Mamalis, D E Manolakos, M B Ioannidis, P K Kostazos, S N Kastanias
This paper deals with the implementation of the explicit Finite Element Code
LS-DYNA to simulate the crush behaviour and energy absorption characteristics of
thin-walled steel tubes of the same length containing a number of geometrical
discontinuities in the form of constant depth grooves.The obtained numerical
results are compared with actual experimental data from small-scale models.

Towards a finite element head model used as a head injury predictive toolInternational Journal of Crashworthiness - Tập 8 - Trang 41-52 - 2003
B Canaple, G Rungen, P Drazetic, E Markiewicz, D Cesari
The aim of this paper concerns the development of a new finite element head
model. A particular attention is focused on the representation of the
skull/brain interface and the use of hyperelastic material is recommended to
represent the cerebro-spinal fluid. The validation of this model is achieved by
the comparison of its response with results obtained from cadaver impact tests.

Carbon skinned aluminium foam nose cones for high performance circuit vehiclesInternational Journal of Crashworthiness - Tập 8 - Trang 107-114 - 2003
E C Chirwa, J Latchford, P Clavell
High performance circuit vehicles such as Formula I and Indy cars, require to
have a structure in front of the survival cell that efficiently absorbs impact
energy in the event of a frontal collision. This structure needs to fit the
strictly prescribed dimensions to be legal and need to absorb kinetic energy in
the range of 45 kJ and above, with an average acceleration of 25 g. The overall
permane... hiện toàn bộ
Measuring rollover roof strength for occupant protectionInternational Journal of Crashworthiness - Tập 8 - Trang 97-105 - 2003
D Friedman, C E Nash
Survival in rollovers requires occupant compartment integrity and good restraint
performance (including use of effective reminders) to prevent ejection and to
protect an occupant's head and neck. We provide a discussion of why roof
strength is critical to survival and present the results of a recent series of
quasi-static tests of roof strength. We then propose a simple, direct dynamic
test of roo... hiện toàn bộ
New injury reference values determined for TRL legform impactor from accident reconstruction testInternational Journal of Crashworthiness - Tập 8 - Trang 179-188 - 2003
Y Matsui
New injury reference values for evaluation of injury risk to pedestrian leg by
means of the legform impactor with rigid leg and thigh developed by the
Transport Research Laboratory (TRL) are proposed in the present study. Lower
extremity responses related to the risk of pedestrian leg injuries induced by
the bumper contact in a real-world pedestrian accident, such as knee angle and
lower leg accel... hiện toàn bộ
