Samenvatting

Full-field identification methods can adequately identify constitutive material parameters, by combining Digital Image Correlation (DIC) with Finite Element (FE) simulation. It is known that interpolation within the DIC procedure is an important error source for DIC-results. In this study, the influence of these errors on the eventual identification results is investigated. Virtual experiments are conducted from which constitutive parameters are identified by two approaches: the commonly used method of Finite Element Model Updating (FEMU) and the more recent method of Integrated Digital Image Correlation (IDIC), in which the utilized interpolation functions are varied, and the influence on the identified parameters is investigated. It was found that image-interpolation has a significant effect on the accuracy of both methods. However, the observed differences in results between the two methods of FEMU and IDIC cannot be explained by interpolation errors.
