Definitions and quantifications of resilient mat stiffness parameters: an investigative look into key aspects of the new DIN Standard 45673 part 5 and part 7

The precise definitions and concomitant quantification methods of resilient mat stiffness parameters are ostensibly simple and uncomplicated. After all, how many resilient mat stiffness parameters can be meaningfully defined from a track engineering point of view and how much influence can stiffness definitions and concomitant quantification methods exert on the...
