Explanation of erroneous
statements about SMAC and CRASH
For
additional information on SMAC,
CRASH and other accident reconstruction and simulation
programs please see the
www.mchenrysoftware.com and the
many technical papers on the website
Over the years, several papers have taken
cheap shots at SMAC or CRASH, some funded by automobile manufacturers, and some as
thinly veiled sales pitches for competing software or services. This page
will contain a list of some of the more onerous papers and our responses to the
papers.
- 1985:
SAE paper 850255,
"Inaccuracies in the CRASH3 Program",by Woolley, Warner & Tagg. For archival purposes we post up our
response to that paper:
- 1997:
SAE paper 970960 "Effects of Restitution in the
Application of Crush Coefficients". For the 1997 SAE congress we published 4 papers and dealt with 8
reviewers as a part of the peer review process. It was a pleasure to work
with 7 of the 8 reviewers and we thank them for taking the time and effort
to review and provide constructive comments on our papers. One of the 8
reviewers made the review process an unreasonable and offensive ordeal and
we post up our documentation of the ordeal.
- 2001:
SAE paper 2001-01-0502: "Stiffness Parameters for Vehicle Collision Analysis, An Update" by Nystrom.
The paper was related to our research. There were a tremendous number of
errors and fundamental misstatements in the paper. We sent a
preliminary reply to the author and SAE Accident reconstruction session chairmen
- 2003:
Low-Speed Automobile Accidents: Accident Reconstruction and
Occupant Kinematics, Dynamics and Biomechanics, Third Edition, from
Lawyers & Judges
Publishing. By author: Alan J. Watts Ph.D. This book, published in 2003 and brought to our
attention in 2004 or so, has a section entitled "Issues to Watch out For" (p
86) where the authors make critical comments on SMAC. The authors apparently
do not understand SMAC or CRASH. Please see our page
which documents some of the errors in the book.
- 2007:
IPTM published a hack job paper in 2007 entitled "Energy,
Momentum and the Chaos of Time" by Bonnett. We include our
response to that paper

Our responses on this page have been presented before. See our
1997 SAE papers for a
