Prediction of Local Ultimate Strain and Toughness of Trabecular Bone Tissue by Raman Material Composition Analysis

Figure 3

Regression analysis for the two donors showing the ultimate strain (a) and the postyield work (b) versus the carbonate substitution ratio. Tensile and bending data are analyzed separately and the Pearson correlation coefficient is reported for each regression line (healthy donor: solid line; osteoporotic donor: dotted line). values for all correlation coefficients are in the range of 0.005–0.047.
