Fig. 120 Temperature dependence of the Poisson's ratio and the elastic moduli of tungsten. Poisson's ratio and elastic moduli calculated from single-crystal elastic constants ( v c , E c , G c , and K c ) and from polycrystalline tungsten ( v p , E p , G p , and K p ). Sources More

... Abstract The design of structural components with nominally brittle materials is largely determined by their elastic moduli, density, and tensile strength. This article discusses some of the factors involved in the design and reliability through considerations of toughness and ductility...

... to the fibers, as well as various Poisson's ratios. This can be done in terms of simple analytical expressions. Elastic properties of homogeneous materials are defined by relations between homogeneous (constant) stress and strain. Because of the various symmetries, there are 21 independent elastic moduli...

... glasses also have relatively high Poisson's ratios of 0.28. Because glasses are isotropic, the shear and bulk moduli can be calculated from the usual formulas. Silica-free glass compositions, such as the phosphates, have weak bonding between chains, which leads to lower values of elastic modulus...

The elastic response follows a linear relation (Hooke's law): (Eq 1) τ = c e where c the tensor containing elastic moduli for the appropriate crystal symmetry...

... class of material occupies a characteristic part of the chart. The log scales allow the longitudinal elastic wave velocity v = ( E /ρ) 1/2 to be plotted as a set of parallel contours. All this is simple enough—just a helpful way of plotting data. However, by choosing the axes and scales...

Relative motion occurs at the biomaterial-tissue interface as a result of a difference in the elastic moduli, and serious deterioration of the biomaterial...
