ABSTRACT
Based on the various properties of polymeric foams such as better resistance to impact, low density, low thermal conductivity, and acoustic attenuation, they have applications in areas like thermal insulation, acoustic isolation, impact absorbers, sandwich structures, packaging, and filters. To control the properties and morphologies of foams, various micromechanical models of foams are available and each deals with various foam parameters, such as cell geometry of foam, type of polymer used, foam density, gas pressure, relative density, etc. Some of the important micro-mechanical models, including finite element modelling of cellular foams, is discussed in this chapter.
