The dynamic mechanical properties of early-strengthened polystyrene(EPS) concrete under 12 hours',24 hours' and 36 hours' maintenance duration were studied using split Hopkinson pressure bar(SHPB) apparatus.The corresponding stress-strain curves were gained and compared with that of EPS concrete under...
As the composition is varied from the pure polystyrene to the pure polyolefin the stress-strain curve changes gradually from one exhibiting brittle fracture to one showing increasingly ductile yield. At a critical concentration that ranges generally from 30 up to 50% polystyrene there is clearly an...

The fracture energy of the sam- ples was obtained by integrating the area under the stress-strain curve. Morphological Observation Samples with about 1 cm length were cut from the Polym. J.. Vol. 32. No. 3, 2000 middle part of the tensile bars, and dipped in liquid ni- trogen for ...
The results for the tensile modulus and strain at break are, for completeness, included in the Supporting Information (Table S2), together with the stress–strain curves for ABS and PS samples (Figures S5 and S6, respectively). The tensile modulus of ABS and PS are not influenced by the pr...
4.2.2. Typical stress–strain behavior A typical stress–strain curve of EPS geofoam under static loading is displayed in Fig. 4.3. The figure generally consists of four distinguishing parts including: zone 1, an initial linear elastic response; zone 2, yielding; zone 3, linear + work hardeni...
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 ...
22 •23 In their report,22 •23 these effects were associated with inhomogeneous stress and resulting strain birefringence. They found the PS sample, ad- hering to the sample tube, to scramble the in- cident polarized radiation. We wish to explain this unusual temperature dependence of ivn...
The test results show several distinctive material characteristics, including a bilinear stress-strain relationship and negative Poisson's ratio that are not common in conventional construction materials. The results of this study can readily be incorporated in detailed analyses of various geotechnical ...
