SCALING CHARACTERISTICS IN THE STRENGTH OF POROUS PLATES
多孔板强度的标度行为

We performed the measurements of the bulk modulus E,yield strength S_y,fracture strength S and fracture work W in randomly punched plates of plexiglass,steeland aluminium.A power law relation is observed for E,S_y,and S near the percolationthreshold and the determined exponents of our samples appear to be considerably lowerthan the theoretical determinations for a bond-bending force system,and hence,thebond-stretching nature of the samples is taken into account to interpret the difference.
