Deformation and Fracture Maps for Cellular Materials and Solid Polymers.

Abstract

The mechanical properties of 3 types of cellular solids (flexible, plastic and brittle) have been measured as a function of density. The results are compared with models for the stiffness, strength and densification; and constitutive laws are developed. Data and models for each type of cellular solid are combined to develop mechanism-mode maps which summarize the properties in a single diagram. Natural cellular materials fit the same pattern; maps are presented, as an example, for wood. The maps help in design and in the selection of materials for load-bearing and energy-absorbing applications. Originator supplied keywords include: Fracture, Polymers.
