Transferring load to flesh. Part VIII. Stasis and stress.
Those who suffer peripheral vascular disease (PVD) frequently require lower-limb amputation. To prevent further difficulties with circuation, the socket and support system of the resulting artificial leg should be arranged so as to prevent impairment of blood flow. The mechanical stress factors tending to impede flow and cause stasis are investigated. An assessment is made of the relative importance of the two types of stress, normal and shear, in reducing the flow within a simulated vessel surrounded by a model flesh.
