Abstract

The mechanical characterisation of laminates is achieved through a methodology based on vibration test measurements. The relation between effective mechanical properties and vibrational characteristics is initially generated by multiple finite element simulations and then approximated through the development of a surrogate model or meta-model. The inverse problem of finding the properties from given experimental data is solved through an iterative optimisation scheme within which the frequencies for a particular set of material parameters are predicted by the meta-model. This results in a versatile and time-saving characterisation process, which can be applied to a large number of specimens with a complicated geometry. Keywords: composites, characterisation, vibration, experiments, metamodelling.
