    Model of the Mechanical Behavior of Cementitious Matrices Reinforced with Nanomaterials by Victor D. Balopoulos, Nikolaos Archontas, Stavroula J. Pantazopoulou

    Published 2017-01-01
    “…Experimental evidence supports this concept; however, testing at the nanoscale may only be conducted through nanoindentation, which has a limited range only providing localized results that cannot be extrapolated to general stress states. To evaluate the restraining action of nanomaterials in the gel microstructure, a computational mechanistic model has been developed where the material phases (gel, nanotubes, and pores) are modeled explicitly allowing for natural randomness in their distribution and orientation. …”
