Flexible polymeric foams are used in many industrial applications, including cushioning, shock absorption, and noise suppression. There have not been many systematic studies on the characterization of their elastic response that can be used in developing their constitutive behavior. This paper presents the uniaxial tensile data of two different flexible polyurethane foams and determines the relationships between their elastic properties and the major stretch ratio. These relationships will be useful in formulating constitutive models for flexible compressible materials.
