The above graph (Fig. 11) and Table 5 describe the zones under observation when the cast-moulded specimen was subjected to the indirect tensile test: Table 5. Observed performance of cast-moulded specimen. RegionTest Status 1 Test bench in contact with the specimen. This zone extends across ...
Next a larger stress is applied to the same test specimen and after recording the strain at time t, this stress is removed and the material is allowed to recover in the same manner. This procedure is repeated until enough points have been obtained for the isochronous graph to be plotted. ...
All the test results have been thrown together on one graph to show how nearly alike are the results for all the steels. Figure 12 seems to indicate that the static crack strength, like the other strength indices is different for the bainites and pearlites; that is, the points of Fig. ...
Test samples were cut by electro-discharge machining from the batch-annealed material. Activation energies for dynamic strain aging were determined by performing tensile tests at different strain rates (\( \dot{\varepsilon } \)) ranging from 10−4 to 10−2 s−1 using a 95 kN servo-...
It must be noted that all the above simulations were merely intended to test the assumptions made earlier regarding the role of transverse and residual stresses and no verification of the experimental results was planned. Indeed, the exact development of residual stresses in the architectured ...
Figure 1. Graphical explanation of test annotation. Table 1. Overview of test program. 2.2. Materials 2.2.1. Concrete For the concrete mix, CEM I 52.5 N Portland Cement and natural aggregates with a maximum size of 16 mm were used. The distribution for all concrete mixes was at 45, ...

Introduction In the last decades, High Strength Steels (HSS) have been introduced in the automotive industry to reduce the weight of vehicles, improve safety, and reduce ...
Collagen patterns were analyzed via a non-parametric Wilcoxon test using averaged results from image replicates for each individual, treatment, and day. Follicle density, stromal score, and gene expression data were analyzed via a non-parametric Wilcoxon test, with the significance threshold value set...
