Dynamic Mechanical Properties of Polyoxymethylene III
Japanese Journal of Applied Physics, 1967Dynamic mechanical measurements of a drawn polyoxymethylene are performed by a torsion pendulum apparatus over a frequency range of 1.0 to 0.005 Hz at various temperatures in the α-dispersion range. Real and imaginary parts of complex rigidity are measured on each of the specimens cut out from the drawn sample at various angles with the draw ...

Studying the influence of temperature and loading frequency on the behavior of syntactic foams is important because of its diverse set of applications. Dynamic mechanical analysis (DMA) is a widely used technique for measuring viscoelastic properties of materials over a range of temperatures and loading frequencies. The storage modulus and loss modulus

Dynamic mechanical properties of dental amalgams
Dental Materials, 1990The dynamic mechanical properties of two high-copper amalgams (Tytin and Dispersalloy) and two traditional amalgams (Aristalloy and Aristalloy with Zn) were measured over a temperature range of 0-70 degrees C and at frequencies of 0.1, 1, and 10 Hz by means of a DuPont DMA.

Dynamic mechanical properties of human lenses
Experimental Eye Research, 2005The purpose of this study was to determine the shear compliance of human crystalline lenses as a function of age and frequency. Dynamic mechanical analysis was performed on 39 human lenses, ranging in age from 18 to 90 years, within the frequency range of 0.001-30 Hz. The lenses were stored at -70 degrees C before being measured.

Dynamic mechanical properties of an inlay composite
Journal of Dentistry, 1989A visible light-cured composite resin (Brilliant DI) has been studied over a wide range of temperature and frequency by a dynamic mechanical flexural method. The derived data of logarithmic modulus and loss tangent (tan delta) show considerable changes following a secondary-cure process applied to the material. This involved the application of heat and

Dynamic Mechanical Properties of Polyisobutylene
Journal of Applied Physics, 1953Values of complex shear compliance (and rigidity) have been obtained for a sample of polyisobutylene of viscosity-average molecular weight 1.35×106 at 22 temperatures from −45 to 100°C and at about 20 frequencies from 30 to 5000 cps. Measurements were made by means of the transducer method of Fitzgerald and Ferry with a precision of ±2 percent and are ...

Dynamic mechanical properties of polymers
Journal of Applied Polymer Science, 1969AbstractA technique, employing samples in the form of tuning forks, to measure the mechanical properties of polymers is presented. Results for low density polyethylene, polypropylene, and polycarbonates are shown. A large transition is observed for polypropylene at approximately +10°C and a small transition at −100°C for the polycarbonates ...

A model for the dynamic mechanical properties of arteries
Journal of Biomechanics, 1972Abstract A phenomenological model is used to represent the frequency dependence of the mechanical properties of arteries. The model was tested on mechanical properties data derived from simultaneous measurements of intra-arterial pressure and external diameter from surgically exposed femoral arteries of anesthetized dogs.
