effect of crushing on a material density

On the effect of relative density on the crushing and ...

Aug 01, 2015  It is widely understood that most mechanical and other properties of cellular materials scale with their relative density see Ref. . Thus the present study examines the effect of the foam relative density on crushing and energy absorption at different loading rates ranging from quasi-static to sub- and super-critical impact velocities.

Aug 21, 2007  [32] When pore collapse and grain crushing take place (at P = P*), the crack density ρ raises from 0 to a mean value of 0.1 (curve 3). An anomalous feature just beyond P * is that crack densities inferred from equations (8) and (9) become different: Inversion of G moduli gives a ρ value close to 0.2, whereas inversion of K moduli data gives a ...
