Abstract
The paper examines the ability of two selected viscoplastic models to reproduce the deterministic size effect in plain concrete specimens. The first one is the concrete damaged plasticity model and it is available in the ABAQUS package. The second one is the Hoffman viscoplastic consistency model and it is programmed in FEAP. Rate dependency existing in both models serves as a localization limiter leading to mesh-objective results for reasonably high values of viscosity, so the reproducing of the deterministic size effect is expected. Numerical analysis is performed for notched and unnotched beams under three point bending using both models. Additionally, the results are compared with the experiment made by Grégoire et al.
