The HSM Part D provides a quantitative measure of safety for various countermeasures known as crash modification factors (CMF). These CMFs are provided for four distinct...

 

Building upon the development of a measure of safety culture based on a simplified two-factor model of meaning and behavior, a further validation study of the safety culture instrument was undertaken. The Safety Culture Assessment Survey (SCAS) was administered to a large regional railroad organization...

 

Ductile fracture has been identified as the predominant mode of failure for structural elements under extreme loads and the prediction of such represents considerable challenges. Until recently, ductile fracture of metals has been recognized to be dependent on both stress triaxiality and Lode angle parameter....
