Unconfined Compressive Strength and

Elasticity Modulus. By extracting the data shown in Figure 5, the peak stress of all samples can be obtained.

Figure 3 shows the effect of temperature on the peak stress and

elasticity modulus. In the natural state, the average values of peak stress and

elasticity modulus are 80.69 MPa and 20.05 GPa, with the dispersion coefficients (namely, the ratio of standard deviation to average value) of 0.03 and 0.13, respectively.

Besides of these, the influence of the type of aggregate on the

elasticity modulus is approached by Ozturan and Cecen (1997), Shi, Mo, and Dhonde (2008), Neto, Oliveira, and Ramos (2011), Uysal (2012), and others.

The dynamic

elasticity modulus can be calculated according to the experience formula (1):

The test result for tensile strength are shown in Figure (4).in addition to Rubber Compound Distinguishing that having (Ti[O.sub.2]) at ratio (60% pphr) that best compound because have best properties of Tensile,

Elasticity Modulus and Elongation, (Satiric acid) adding to compound and frome figure that show simple increasing from Tensile in simple ratio of (Satiric acid) but cross linking increase between (Satiric acid, Ti[O.sub.2]) and cross linking between (Satiric acid, Ti[O.sub.2]) and Rubber Chain, but after (80% pphr) from (Satiric acid) notice tensile decrease When Rubber chain cannot having Filler practice.

Eurocode 6 gives a relation between the

Elasticity modulus of masonry (E) and its characteristic compressive strength: E = [K.sub.E]/[f.sub.k], with [K.sub.E] = 1000.

Then the effect of dimensions and

elasticity modulus of the fiber buddle on the stress intensity factor (SIF) of the matrix crack is studied numerically.

The red cell membrane

elasticity modulus characterizes its average stiffness, within our study over the entire adaptation period it was significantly below the value in the control group by 57-63%.

The

elasticity modulus was calculated from an inclination of an elastic part on proportionality of stress to strain curves by ~2.0% offset.

In the case of the last, higher specific surface means higher mechanical values, for example, (a) polymer concrete with clean sand have higher values than those with foundry sand [5]; (b) for concrete elaborated with epoxyresin, silica sand, hematite, and colemanite, the mechanical properties depend on the resin and hematite-colemanite concentrations; larger improvement for hematite is done [6]; (c) for concrete with waste marble as aggregate the splitting tensile strength decreases, and improvement on the

elasticity modulus is produced [7].

The effects of thickness and

elasticity modulus of mudstone interbed were discussed, respectively.
