It had been long recognized that the tensile strength of brittle materials
increases with increase of the loading rate. In the present article, a statistical
approach to rupture of a disordered 2D triangular truss lattice consisting of fragile
nonlinear springs is attempted in hope to elucidate some generic effects of structural
and geometrical disorder on the tensile strength and the (stress-peak and post-peak)
damage energy rates. The simulation results reveal increase of the mean and decrease
of the standard deviation of the macroscopic tensile strength with increase of the
structural and geometrical order till the ‘theoretical strength’ saturation. At the same
time, the increase in lattice disorder results in increase of the mean and standard
deviation of the stress-peak damage energy rate, followed by the decrease of the same
in the softening regime.
