Fig. 2From: Dynamic viscoelastic characterisation of human osteochondral tissue: understanding the effect of the cartilage-bone interfaceCartilage hysteresis. Force is given as increase in force during loading cycle. a Example of hysteresis loop generated for a single specimen at 30 Hz. b Approximation of the area between the upper and lower arcs of each cycle calculated using the trapezoidal rule. The difference between the two areas was determined as the total energy dissipated during that cycle of DMABack to article page
