Wh. Elratal et Pk. Mallick, ELASTIC RESPONSE OF FLEXIBLE POLYURETHANE FOAMS IN UNIAXIAL TENSION, Journal of engineering materials and technology, 118(2), 1996, pp. 157-161
Flexible polymeric foams are used in many industrial applications, inc
luding cushioning, shock absorption, and noise suppression. There have
not been many systematic studies on the characterization of their ela
stic response that can be used in developing their constitutive behavi
or. This paper presents the uniaxial tensile data of two different fle
xible polyurethane forms and determines the relationships between thei
r elastic properties and the major stretch ratio. These relationships
will be useful in formulating constitutive models for flexible compres
sible materials.
