Density, Microstructure, and Strain-Rate Effects on the Compressive Response of Polyurethane Foams

A better understanding of the effect of density, microstructure, and strain rate on the mechanical response of polymeric foam materials is needed to improve their performance. The objective of this paper is to study the combined influence of density, microstructure, and strain-rate on the compressive stress-strain response of polymeric foams. Microstructural morphological parameters (e.g., pores sizes and wall thicknesses) have been quantified...
