... density, confining stress and displacement rate. Finally, based on the triaxial test results, a set of equations was proposed to estimate the compressive behavior of EPS and the accuracy of the equations was assessed by comparisons with experimental results. As shown in Figure 2 , the compressive...

...J.P. Giroud; L.G. Tisinger A relationship between the density of a polyvinyl chloride (PVC) geomembrane and its plasticizer content is established. Approximate linear relationships are proposed, and a numerical application is presented. Equations derived from the density-plasticizer content...

...J.P. Giroud A theoretical relationship is established between the density of a polymeric geomembrane, the density of the polymer, the density of carbon black, and the carbon black content. Then an approximate relationship is established for polyethylene geomembranes. For the usual range...
