Sound speed, longitudinal

This is expressed in terms of the particle acceleration immediately behind the shock front. Equation (A. 15) can be expressed in terms of the Lagrangian stress gradient (dff/dX), and the Lagrangian longitudinal sound speed Q =... [Pg.262]

The longitudinal sound speed is appropriate for the tail of the rarefaction. If you do not have a value for this speed. Cl can be estimated by using a value for a similar material in a similar state of aggregation. The values used for the... [Pg.227]

Solution We know that for this problem we will need values for both the U-u Hugoniot as well as the longitudinal sound speed for stainless steel. We can get these from Tables 17.1 and 17.3. From Table 17.1 we have for 304 stainless steel... [Pg.244]

The longitudinal sound speed in the polymer can be determined by measuring the time required for a pulse propagated normally into the sample to reflect from its far surface (usually a polymer/air interface where the impedance mismatch generates a reflected wave), and dividing the sample s thickness by twice this time. The time is determined by the interval between the initial pulse and the successive reflections, which result as the wave bounces... [Pg.1024]

Elastic Constants. One of the purposes of measuring soimd speeds is to determine the elastic constants of the polymer. Longitudinal sound speed vi, and shear soimd speed Vg are related to elastic constants hy... [Pg.44]

In applying Rao s rule to solid polymers, it should be kept in mind that the longitudinal sound speed (eq. 1) includes not only a bulk modulus term, but also a shear modulus term that must be taken into account (5). This has been done for both linear and cross-linked polymers (44-47). Van Krevelen has named the additive variable for bulk modulus the Rao function, Ur, and for shear modulus the... [Pg.55]
