摘要: Hard systems of nanocoatings deposited using PVD (physical vapor deposition) are used in the artificial heart prosthesis. Correct determination nanomaterial parameters is crucial for accuracy simulation. The objective this work identification material hard system inverse analysis based on neural network metamodeling. was preceded by development Finite Element Method (FEM) model dedicated to nanoindentation test system. performed sensitivity focused parameters, having highest influence FEM response. obtained, reliable next analysis. that evaluation individual layers nanocoating In order decrease computation time connected with analysis, metamodeling approach proposed. metamodel technique. obtained results confirm usefulness presented method properties complex, systems.
