This study aimed at indexing crash worthiness capability of 20 most frequently used car brands in Iran. Since rollover crashes are one of the most important crash types due to their high impact on crash severity, they were chosen as the case study of the current research. In this regard, the data of 42,118 rollover crashes of urban and rural roads of Iran which occurred from 2009 to 2012 was us...

1 I n t r o d u c t i o n Safety measures like airbags and safety belts are nowadays commonly applied to improve the crash worthiness of road vehicles. Many governments stimulate or oblige by law car producers to include these devices in the vehicle design. Maximum values are imposed on parameters that quantitatively describe the severity of injuries. Examples are the Head Injury Criterion (HIC...

Finite element post-processing has been dominated by software that is tightly integrated with simulation packages. Many of these packages have not kept up with the state-of-the-art developments in graphics technology and visualization techniques. Especially the large and time-dependent data sets resulting from crash-worthiness simulations in the automotive development process demand for new vis...

Abstract The crash-worthiness design of civil transport aircraft fuel systems is significance to improve the safety in case a crash. CCAR25.993 (f) requires that “fuel feed line fuselage shall be assembled allow reasonable deformation and tension without leakage”. Fuel system supply with appropriate hose configuration can take advantage ductility material, guillotine test accepted by worldwide ...

Since crash-worthiness simulations get more and more important as part of the car development process in order to reduce the cost of development, enhance the product quality, and minimize the time-to-market, the reliability of the simulation results plays a decisive role concerning their significance. Recently the simulation departments of several automotive companies started investigating the ...

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...

The production of closed-cell metallic foams has been interest to the scientific community and industry for decades, owing their unique properties, which include high specific strength stiffness, buoyancy, shock absorption, crash worthiness. One approaches fabrication relies solely on use powders is manifested in what referred as powder metallurgy (PM) route. This review discusses underlying fu...

Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load depend on many parameters including ...
