In Fig. 7.19, data are converted into velocities (m/s) and redrawn as a plot of uniaxial compression strength versus compressional wave velocity. Two... 

With the help of these equations the uniaxial compressive strength/elastic modulus of jointed rocks can be determined for known values ofjoint factor and uniaxial compressive strength/elastic modulus of intact rock. It is observed that the ratios of both static and dynamic elastic modulus decreases with an increase inthe jointfactorunder unconfinement. The test results of POP and the POP-cement mix specimens are given in Table 5. Figure 14 shows the experimental values of uniaxial compressive strength ratio versus joint factor along with a fitted curve.

Figure 7.27 shows examples of forward-calculated uniaxial compression strength as a function of porosity curve parameter is the structure angle (you find for the calculations an Excel worksheet in the folder Elastic-mechanical, structured model/Fp versus Strength on the website http // booksite.elsevier.com/9780081004043/). 

During the granulation experiments samples were taken at constant time intervals. For each sample the particle size distribution was analyzed by means of a Camsizer (see Section 5.2.2 in Volume 2 of this series). Additionally, the mechanical strength was determined per uniaxial compression (see Chapter 6 in Volume 2 of this series). The results are visualized by plotting the breakage probability versus the breakage energy, similarly to the plot of Fig. 7.12 of Section 7.3.1.
