Abstract
The mechanical behavior of cellular solids is determined by their structure and the mechanical behavior of their constituents. Cellular plastics in particular are available with a broad range of mechanical response because they can be produced with substantially different cell structure and they can also be produced from substantially different polymers. The practical desire to engineer cellular plastics, which we will also refer to as foams, motivates the investigation of structure-property relations. This chapter focuses on the development of theoretical models to predict and understand the connection between the cellular structure of foamed materials and the mechanical response under a broad range of deformation conditions. The micromechanical theories that will be described provide a complete description of deformation and stress on both the microscopic scale of the cells and the macroscopic scale of the foam. This permits one to identify those features of foam morphology and the corresponding micromechanical mechanisms that control global mechanical behavior.
