Abstract

In the contribution at hand, a new material modelling approach is introduced. This formulation is based upon the Principle of Multiscale Virtual Power and consideration of micromechanically motivated assumptions. Consequently, the evolution of dissipative phenomena depends on the chosen microstructure. Therefore, a strong anisotropy, which is induced by damage, is represented even with isotropic material formulations. This phenomenon is present in concrete.
Furthermore, the modelling approach is validated by different material tests. Tensile-tensile and compression-tensile tests are used for validation of the proposed description. Some material tests are taken from the existing literature, while others are presented in the contribution at hand. Furthermore, the capabilities of the proposed formulation to capture different amounts of textile reinforcement in concrete are shown by additional experiments from the literature. Subsequently, the consistent linearisation of the proposed model is verified based on numerical analyses.
