NASA is developing a new crewed vehicle and desires a lower risk of injury compared to automotive or commercial aviation. Through an agreement with the National Association of Stock Car Auto Racing, Inc. (NASCAR®), an analysis of NASCAR impacts was performed to develop new injury assessment reference values (IARV) that may be more relevant to NASA's context of vehicle landing operations. Hea...

Traumatic rupture of the aorta (TRA) is one of the leading causes of death in automotive crashes. The risk of fatality is higher if the injury is not detected and treated promptly. Numerous laboratory experiments and retrospective studies with focus on TRA have yielded limited success. The use of numerical surrogates has become increasingly important in investigating injuries such as TRA. Four ...

BACKGROUND Tranexamic acid prevents blood clots from breaking down and reduces bleeding. However, it is uncertain whether tranexamic acid is effective in traumatic brain injury. The CRASH-3 trial is a randomised controlled trial that will examine the effect of tranexamic acid (versus placebo) on death and disability in 13,000 patients with traumatic brain injury. The CRASH-3 trial hypothesizes ...

Todays car body models used for crash-worthiness simulations consist of around half a million nite elements. The interactive visualization of these large scale time-dependent geometries with constant topology on workstation platforms requires a variety of modeling and rendering optimizations. We present a memory eecient scene graph design, an algorithm to concatenate the mainly four-sided eleme...

Previous studies have shown that the correct use of car safety seats can protect infants and children from vehicular injury. Although child passenger devices are increasingly used in the US, motor vehicle crashes continue to be the leading cause of death and acquired disability in infants and children younger than 14 years of age. These events are likely related, at least in part, to the high p...

The LS-DYNA nonlinear finite element analysis software package developed for structural analysis by the Livermore Software Technology Corporation (LSTC) is widely used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries. Fujitsu has been a partner with LSTC since 1996, supporting customers in Japan. A common application of LS-DYNA is car crash simu...
