Cortical bone undergoes a uniaxial compressive strain of 0.2 percent in a confined compression state (the bone can only change dimensions in the loading direction). Given the on-axis elastic properties for femoral cortical bone in the table below, determine the following: a.) Calculate values for all stresses that develop when a uniaxial compressive strain of 0.2 percent is applied. b.) Repeat (a), but assume isotropic conditions. Use the elastic modulus in the stiffest direction and a Poisson's ratio of 0.3 (as commonly used for many structural analyses of cortical bone. c.) Compare your results from parts a and b, and comment on the importance of anisotropy of cortical bone in structural applications. -033 -033 3 1 Elastic constant E₁ E₂ E3 G₁2 G23 G31 V12 V₂3 V31 Unit GPa GPa GPa GPa GPa GPa Value 12.0 13.4 20.0 4.53 6.23 5.61 0.376 0.235 0.371 Cortical bone undergoes a uniaxial compressive strain of 0.2 percent in a confined compression state (the bone can only change dimensions in the loading direction).
