WebLung hysteresis can be quantified because it applies to the area between the … The lung is an imperfect elastic body and for this reason dissipates energy. The energy applied to the lung in inspiration is not recovered in expiration. The property of dissipating energy receives the name of hysteresis. Lung hysteresis can be quantified because ... WebJan 8, 2024 · Think of Hysteresis as the amount of 'deformation' a piece of rubber is capable of, rubber being an elastic/deformable material, and specifically tread rubber, when it comes in contact with the irregularities …
WebHow to use hysteresis in a sentence. a retardation of an effect when the forces acting upon a body are changed (as if from viscosity or internal friction); especially : a lagging in … Elastic hysteresis In the elastic hysteresis of rubber, the area in the centre of a hysteresis loop is the energy dissipated due to material internal friction. Elastic hysteresis was one of the first types of hysteresis to be examined. The effect can be demonstrated using a rubber band with weights attached to it. … See more Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a … See more Rate-dependent One type of hysteresis is a lag between input and output.
