Calculation of Indentation Hardness Based on Indentation Energy
Comparing advantages and disadvantages of Oliver-Pharr method, microhardness method and indentation energy method, this article propses the improvement of indentation energy method. The improvement of indentation energy method mainly takes the calculation of energy and pile-up and sink-in phenomenon into account. Using Abaqus to simulate the indentation of aluminum with Vicker indenter, process and analyse data from simulation . By comparing different methods of hardness calculation , analyse the effect of improvement of hardness calculation.
