The dynamic mechanical properties of human skin in vivo
Journal of Biomechanics, 1983The propagation and attenuation of shear waves in human skin is investigated over a frequency range of near zero to 1000 Hz. The results show that at frequencies below a few hundred Hz, shear waves propagate along the skin surface and thus provide information on the dynamic mechanical properties of the stratum corneum.

Acoustic and dynamic mechanical properties of a polyurethane rubber
The Journal of the Acoustical Society of America, 2002Acoustical and dynamic mechanical measurements were carried out on a commercial polyurethane rubber, DeSoto PR1547. The sound speed and attenuation were measured over the range from 12.5 to 75 kHz and 3.9 to 33.6 °C. Shear modulus was measured from 10−4 to 2 Hz and −36 to 34 °C.

The dynamic mechanical properties of nylons
Journal of Applied Polymer Science, 1959AbstractA study of the dynamic mechanical properties of a series of polyamide polymers and some related polymers has been made over a wide temperature range at about 100 cycles/sec. by means of a vibrating reed method. The character of the β dispersion of the polyamides occurring at about −40°C. is discussed in relation to the chemical structure of the

Dynamic Mechanical and Tensile Properties
2012DYNAMIC MECHANICAL AND TENSILE PROPERTIES are determined in all branches of materials science. There is a large body of published structure/property information that can be integrated with coatings research and development. By using structure/property information, coatings chemists can design and optimize chemical structures of the binder components of

Measurement of Dynamic Mechanical Properties
1980Measurements of dynamic mechanical properties of viscoelastic materials have been reviewed. The technology for investigating the dynamic mechanical properties of materials has advanced greatly due to new electronic circuits, improved transducers, signal receiving systems, and computerized controlling systems.

Postmortem transition in the dynamic mechanical properties of bone
Medical Physics, 1977Measurements of dynamic shear compliance versus dead time at room temperatures are reported for a sample of rabbit bone and several samples of human bone, including an extracted wisdom tooth. In all cases an abrupt, second‐order transition is observed in one or both components of the audio‐frequency complex shear compliance, , at about 5 hours after ...
