Abstract Scope |
Nanoindentation test is a method that can measure the mechanical properties of the local region by applying compressive force. This method is effective on measuring the material properties of the multi-phase material or film layer. In this study, an artificial neural network model was trained to extract a stress-strain curve from load-displacement curve of a nanoindentation experiment using finite element method simulation. Target parameters were four mechanical property parameters of Ludwik's equation and the performance of model has been improved through strain distribution and load-displacement curve analysis. The performance of the artificial neural network model was verified with nanoindentation experiments on 304L stainless steel. |
