Finite Element Modeling of a Rockman Portable Dynamic Hardness Tester
A Rockman hardness tester is a type of portable dynamic hardness tester that is similar to a standard Rockwell hardness tester, except the full load is applied dynamically over a very short duration. Finite element models were developed for a Rockman hardness tester and a standard B scale Rockwell hardness tester. The Rockwell hardness tester model served as a benchmark problem to validate assumptions and modeling techniques used for the Rockman hardness tester model. Before developing the model of the Rockman hardness tester, the dynamic loading characteristics were determined using a piezoelectric force transducer. After solving both models comparisons were drawn between the two hardness testers.
