Experimental Observation on the Pure Torsional Ratchetting of Polycarbonate Polymer at Room Temperature

<div>Results of stress-controlled cyclic tests: (a) stress-strain hysteresis of stress level 35 ± 30 MPa and stress rate at 1 MPa/s; (b) evolution ratchetting strain versus number of cycles with different mean stresses and the same shear stress amplitude.</div>
