Highlights A new finite element micromechanical modelling approach for mastics is proposed. The approach allows predicting the viscoelastic properties of mastic from its composition. Model predictions are validated with DSR measurements on four mastic materials. The measurements are performed in temperature interval from 0° to 10 °C for a wide range of filler concentrations. The proposed model captures the measured viscoelastic behaviour of mastic for the full range of material parameters examined.
Abstract A new micromechanical model for predicting viscoelastic properties of mastic is proposed and validated with experiments. The developed model is based on the finite element method and allows predicting the viscoelastic properties of mastic by means of the fundamental mechanical and geometrical properties of its constituents. The influence of modelling parameters on the model’s accuracy is evaluated and optimal parameter combinations are identified. It is shown that the proposed model can capture the measured viscoelastic behaviour of mastics for the range of loading, temperature and material parameters examined. Accordingly, it may be a useful tool for optimizing mastics material design meeting the target viscoelastic properties.
