"when performance counts"






REC-TEC software makes 20 separate C measurements available and each of them can be either equidistant or non-equidistant as the user selects.  In addition each of the elements (1-19) of the damage profile can be independently adjusted for resistance to damage.

Now several more innovative changes are available as user selectable options within the REC-TEC software in the CRUSH5 section.  These changes include dividing the individual elements created by two adjacent C measurements into three distinct zones.  Furthermore, the zones can be individually weighted as their resistance to damage dictates.

Analysis of these new changes will reveal that, while they may be slightly different, they bear a remarkable resemblance to what came before and are now accepted as substantial improvements in the original CRASH3 model.  Is creating separate zones of resistance within each damage element really that far removed from weighting the individual damage elements within the damage profile based on the elements resistance to damage?  Is creating these zones based on percent of the C measurement, or on absolute measurements that need not be equal, really that different from creating elements constructed using non-equidistant C measurements?  In effect, all that has actually been done is to use the innovative changes, which were on a macro scale, and apply those same principles on a micro scale within the damage framework.

Creating these independent zones of resistance to damage in the same direction as the depth of the damage penetration, not only enables a more accurate modeling of the resistance to damage, it removes the rectangular-vehicle assumption in the CRASH3 model.  CRASH3 can be used on the rectangular vehicles populating the highways and byways of the world. CRUSH5 can be used not only on these, but on all the curvaceous sporty little creatures that grace the roadways as well.
