Due to their mechanical and optical properties UV-curable adhesives, available in different compositions, are considered very promising in structural glass design. Especially in the field of transparent facades they could play an important role. However, a product with a wide use in glass construction is still missing and therefore, there is a need of research within this field. In this work, the numerical modelling of various adhesives based on experimental data is investigated. For this purpose, results from DMTA and uniaxial tensile tests are evaluated and used to calibrate respective material models. These models must be capable of describing the stress and strain relation within the regime of finite strains. The most promising model of each composition will subsequently be used to predict the respective material behavior. By comparing the numerical results to the experimental data, the accuracy of each of the models is elaborated and discussed. Subsequently, fields of application of these models in engineering practice are emphasized.
