Correction of indentation load–depth curve based on elastic deformation of sharp indenter

On the value of test data for reducing uncertainty in material models: Computational framework and application to spherical indentation

“…Thanks to recent developments in inverse identification methods, indentation tests, which are often used to measure or compare the hardness of materials, are also being employed to identify the mechanical behavior of the materials in a broader sense [17][18][19][40][41][42][43][44][45][46][47][48][49][50][51]. While indentation test responses may be used to infer different material models, in this study, we opt for the elastoplastic material model characterization with a focus on the influence of different uncertainty sources on the uncertainty of the inferred hardening material model parameters.…”
