Fig. 10From: Mechanical properties of “flexure wood”: compressive stresses in living trees improve the mechanical resilience of wood and its resistance to damageExperimental dampened sinusoidal signal from the incremental angular position sensor. αinitial stands for the initial position of the pendulum and αfinal is the final position of the pendulum after the breakage of the millimetric beam. The difference between these two positions, Δα, corresponds to the difference of potential energy that matches the total energy dissipated during the test, ΔEBack to article page
