Query: On role of matrix behavior in compressive fracture of bovine cortical
  bone   In compressive fracture of dry plexiform bone, we examine the individual
roles of overall mean porosity, the connectivity of the porosity network, and
the elastic as well as the failure properties of the non-porous matrix, using a
random spring network model. Porosity network structure is shown to reduce the
compressive strength by upto 30%. However, the load bearing capacity increases
with increase in either of the matrix properties - elastic modulus or failure
strain threshold. To validate the porosity-based RSNM model with available
experimental data, bone-specific failure strain thresholds for the ideal matrix
of similar elastic properties were estimated to be within 60% of each other.
Further, we observe the avalanche size exponents to be independent of the
bone-dependent parameters as well as the structure of the porosity network.
