Path-Dependent Maximum Range (PDMR)

How It Works

Battelle PDMR begins by seeking the maximum possible distance -- the range -- between any two points in the equivalent stress/strain space over a given fatigue loading history. At the same time, it identifies associated loading path-length. The process continues recursively until each loading path has been counted. Battelle PDMR then collects the cycles calculated and the related path-lengths for subsequent fatigue damage calculation.

Battelle PDMR duplicates precisely the standard set by the American Society for Testing and Materials (ASTM) for rain flow-counting of uniaxial data.

Extensive experimentation and data correlation have demonstrated Battelle PDMR’s accuracy, effectiveness and predictive capabilities. Battelle also works closely with leading software partners such as Abaqus and Fe-Safe™ to ensure optimal interfacing. Battelle offers technical support, consulting, and basic and advanced training courses focused on fatigue and welding.
