WebHere, we used the speed of elastic waves travelling through the skin to obtain measurements from 78 volunteers ranging in age from 3 to 93 years old. Using a Bayesian framework allowed us to analyse the effect that age, gender and level of skin tension have on the skin anisotropy and stiffness. First, we propose a new measurement of … WebCompressional waves in horizontally layered media exhibit very weak long‐wave anisotropy for short offset seismic data within the physically relevant range of parameters. Shear waves have much stronger anisotropic behavior. Our results generalize the analogous results of Krey and Helbig (1956) in several respects: (1) The inequality derived by Postma (1955) … WebElastic anisotropy describes a medium whose stress-strain relationships at any one 3-D location are functions of orientation. By contrast, elastic heterogeneity is the stress-strain variation from point to point within 3-D space.
