Fig. 1From: Printing tissue-engineered scaffolds made of polycaprolactone and nano-hydroxyapatite with mechanical properties appropriate for trabecular bone substitutesA representative stress–strain curve of PCL/30% (wt.) nHAp after compression test displaying three main regions of elastic, plateau, and densification. The point Sy pertains to yield strength and \(\frac{\Delta \sigma }{\Delta \varepsilon }\) pertains to the slope of linear stage in the elastic region of stress–strain curve used to derive apparent elastic modulus (E)Back to article page
