Abstract

Polymeric foams have been widely utilized in packaging and transportation applications due to their light weight but superior energy absorption capabilities. Here the superior energy absorption is usually recognized when the foams are subjected to compression. The polymeric foams possess load-bearing capability under large deformation in compression; whereas, such a load-bearing capability may be lost when the foams are subjected to tensile loading [1]. Dynamic compressive response of foam materials has been extensively characterized, mostly with Kolsky compression bar techniques. However, dynamic tensile characterization of foam materials has been less touched due to the difficulties in dynamic tension techniques. In this study, we employed a 0.26×103 kg/m3 PMDI foam as an example to explore the dynamic tensile characterization of foam materials with our newly developed Kolsky tension bar [2, 3].
