Characterization of the Tensile Behavior of Expanded Polystyrene Foam as a Function of Density and Strain Rate 2020 Access copy available to the general public Unrestricted Expanded polystyrene (EPS) foam is a material, frequently used in a range of applications for its good energy absorption, thermal insulation, durability, and acoustic absorption. In this wide range of applications, the material undergoes a variety of loads that can extend from static to dynamic. When it comes to crush applications, these loading profiles create the need of well-defined compression and tensile properties for a range of densities and strain rates. Herein, static and dynamic tension tests are conducted on EPS foam dog-bone samples for material characterization. The target of the study is to obtain stress–strain curves for a range of densities spreading from 60 to 120 g L-1. For the low-strain rates, tensile testing machines are used, whereas for the high-strain rates, a modified drop tower set-up is used. The influence of the strain rate on the stress–strain behavior, the dynamic strength, Young''s modulus, and energy absorption capacities for different foam densities is measured. Furthermore, the experimental results for each density are compared with the predictions of Avalle''s model for crushable foams to evaluate the validity of the model. The quality of fit obtained between experimental and theoretical is between 70% and 97% depending on the strain rate. info:eu-repo/grantAgreement/EC/H2020/642662/EU/Head protection: a European training network for Advanced Designs in Safety/HEADS This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 642662-HEADS info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.862 2020 MATERIALS SCIENCE, MULTIDISCIPLINARY 141 / 333 = 0.423 2020 Q2 T2 0.937 2020 Materials Science (miscellaneous) 2020 Q1 Condensed Matter Physics 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion De Bruyne, G.
