Compressive properties of EPS foamed concrete with bulk density 300–500 kg/m3 were investigated by stress-strain curve. It’s demonstrated that the compressive strength ranges from 0.7 to 2.5MPa, which is higher than that of similar products. Furthermore, low elastic module and high residual to...
The existing model was improved to avoid the negative volume error which occurs due the large deformation in the foam. To prevent this error, the stress strain curve was extended exponentially at large strains [17]. The extended curve is shown in Figure9. Also, one point integration solid ele...
The load-reducing material is EPS, and its compressible stress-strain curve of EPS is shown in Figure 2. The physical parameters of standard sand and EPS are given in Tables 1 and 2, respectively. Figure 1 Open in figure viewerPowerPoint Gradation curve. Figure 2 Open in figure viewer...
It is not difficult to see that the rABS/rHIPS blends has the smallest stress-strain curve area. Moreover, the area of the stress-strain curve increases gradually after the addition of SBG, which reflects the transition from brittle material to ductile material in the whole process. The ...
Master curves for the biaxial stress growth coefficient η deviates from a linear viscoelastic curve at very small strain such as 0.1, and then approaches a quasi steady state. The quasi-steady-state viscosity ηB,qs decreases with the strain rate ηB. At very small strain rates...
stretch ratio (λ) curve shown in Fig. 2, consisting of (i) an initial viscoelastic regime (shaded region), (ii) a long plateau flow stress regime due to the formation and propagation of a stable neck, and (iii) a pronounced strain hardening regime after completion of neck propagation ...
As shown in Figure 1c, the stress-strain curve changes irregularly with the foaming pressure. In addition, the sample density changes with the increase in the foaming pressure (28). However, as shown in Figure 1d, the compressive elastic modulus and compressive strength of the PS-MCF ...
