Dynamic Tensile Characterization of Foam Materials
msra(2011)
摘要
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].
