Torsion modulus using the technique of mechanical spectroscopy in biomaterials
This work presents a new alternative to studying and determining the shear or torsion modulus, G. For this purpose, a measuring system was constructed with a rotational motion sensor coupled to a torsion pendulum that allowed the determination of the angular position as a function of time.

| Sumario: | This work presents a new alternative to studying and determining the shear or torsion modulus, G. For this purpose, a measuring system was constructed with a rotational motion sensor coupled to a torsion pendulum that allowed the determination of the angular position as a function of time. Through an equation derived from studies of mechanical spectroscopy and the theory of relaxation of materials, G was calculated, and experiments were focused on validating it. The advantage of this technique, compared to other dynamical methods, is that it is not necessary to know the Poisson’s ratio of the sample. |
