Numerous methods have been used to measure elastic moduli. Probably the most common test is the tensile stress-strain test (8-10). For isotropic materials. Young s modulus is the initial slope of the true stress vs. strain curve. That is,... [Pg.36]

Another important factor for tensile testing is cyclic testing or applying force and releasing (or relaxing) force on a test specimen to evaluate its ability to endure cyclic fatigue. A typical stress vs. strain relationship is shown in Fig. 3.16 and a cyclic stress relationship in Fig. 3.17. [Pg.86]

Mechanical Tensile Studies. The simple stress vs. strain characteristics of two-phase materials and their variation with relative phase composition can usually be given straightforward interpretation in terms of critical underlying structural factors. Among these factors can be listed topological connectivily of, and interfacial interaction between the phases. [Pg.405]

Mechanical Tensile Studies. The stress vs. strain curves for membranes having various silicon oxide solid uptakes for the four alcohol solvents are displayed in Figures 3-6. Also shown, for reference, on each of these figures is the tensile behavior of untreated Nafion in the dry add form. [Pg.407]

As discussed in Sect. 4, in the fluid, MCT-ITT flnds a linear or Newtonian regime in the limit y 0, where it recovers the standard MCT approximation for Newtonian viscosity rio of a viscoelastic fluid [2, 38]. Hence a yrio holds for Pe 1, as shown in Fig. 13, where Pe calculated with the structural relaxation time T is included. As discussed, the growth of T (asymptotically) dominates all transport coefficients of the colloidal suspension and causes a proportional increase in the viscosity j]. For Pe > 1, the non-linear viscosity shear thins, and a increases sublin-early with y. The stress vs strain rate plot in Fig. 13 clearly exhibits a broad crossover between the linear Newtonian and a much weaker (asymptotically) y-independent variation of the stress. In the fluid, the flow curve takes a S-shape in double logarithmic representation, while in the glass it is bent upward only. [Pg.97]

According to figs. 10a and 10b, the stress exponents where calculated from the slope of the creep stress vs. strain rate curves. The n value for creep of the Ti5Si3 compound is n=3.0 0.2. This predicts a power law creep behavior based on viscous glide of dislocations sustained by diffusion... [Pg.299]

Nondestructive tests have certain advantages Including the ability to measure the elasticity of the gel on products such as jellies containing particulates. Nondestructive tests can be used to blend raw pectins to a consistent jelly grade. Also, some reports have found nondestructive Instruments to be less expensive and more reliable (63). Mitchell (60) reported that large deformations outside the linear region of a stress vs. strain curve are more difficult to Interpret and more difficult to measure than small deformations because rupture occurs at a defect In the gel and large deformations are not as reproducible. [Pg.96]

Isometric curves are obtained by plotting stress vs. time for a constant strain isochronous curves are obtained by plotting stress vs. strain for a constant time of loading. These curves may be obtained from the creep curves by taking a constant-strain section and a constant-time section, respectively, through the creep curves and replotting the data, as shown in Eigure 3.17. [Pg.298]

The general behaviour is characterized by a decrease of the initial modulus as well as the yield stress with temperatiue. Yielding of the material is finished at a strain of about 600. .. 900 %, afterwards there is a strain hardening. The strain hardening modulus (slop>e of the true stress vs. strain curve in the region of strain hardening) decreases with the temperature. [Pg.465]
