NEW REVISION
Anatomy of the Collision:
IPTM has recently published the 3rd edition of George Bonnett’s Anatomy of
a Collision, first introduced in 1999. The author revised the manual in 2007
by added chapters dealing with stiffness coefficients, the problem with turns,
the problem with constants, beyond Crash3, and understanding delta V from
damage. He has expanded the text once again to include chapters focusing on
pedestrian vaults, basic photogrammetry and the myths and misconceptions
associated with momentum. The basis of the book – the 8 collisions having a total of 44 variants – is
retained from the original work. They are each examined in detail with respect
to energy, restitution, momentum and damage. The in-depth analysis using
different approach and departure angles, different speeds and weights, and
different restitution values provides you with a critical look at how momentum,
energy and restitution influence the mechanics of a collision. Since the material covered aggressively deals with the hard questions that
plague all reconstructionists, you will still be able to find the examination of
formulas for both restitution and energy from translational and rotational
motion, a discussion of delta V from damage, secondary slap, coefficients of
lift and drag, rotation, inertia, uniform circular motion and the calculation of
PDOF angles. George Bonnett is a combat-proven Marine Corps aviator turned police officer,
turned attorney, turned crash reconstructionist, turned software developer (REC-TEC).
For George, survival and success have always depended on resourcefulness and
minute attention to detail. You will find these qualities very much alive in
this 2007 edition. Price: $44.95 |
