Model of the Mechanical Behavior of Cementitious Matrices Reinforced with Nanomaterials

Figure 3

Individual response curves of unreinforced discrete specimens ( MHD) to uniaxial plane-stress loading, along with sample mean response curves (solid black line) and 2σ-envelopes (dashed dotted black line). Stresses and moduli of elasticity are made comparable across samples by division with the observed volume density / of each specimen (given in parenthesis in the legend). (a) Stress in direction of loading. (b) Secant modulus of elasticity. (c) Stress across loading (zero throughout). (d) Secant Poisson ratio (apparent incompressibility observed at limit point in compression).
