Mechanical properties of Mammuthus primigenius tusk dentine. (a) Bending strength and Young’s modulus for longitudinal and transversal samples. (b) Stress-strain diagram for longitudinal and transversal samples. (c) Gradients of the bending strength for longitudinal and transversal samples as a function of their position within the tusk. No scale. (d) Gradients of Young’s modulus for longitudinal and transversal samples as a function of their position within the tusk. No scale.
