Confined compression tests up to 70% of deformation have been performed on polyurethane foams. During these experiments strain localization has been observed (Pampolini et al. 2007-2). This behavior is described by a one-dimensional model, in which the foam is represented as a chain of non-linear elastic springs with a double-well strain energy density, and the localization is attributed to progressive phase change.

Abstract

Confined compression tests up to 70% of deformation have been performed on polyurethane foams. During these experiments strain localization has been observed (Pampolini et al. 2007-2). This behavior is described by a one-dimensional model, in which the foam is represented as a chain of non-linear elastic springs with a double-well strain energy density, and the localization is attributed to progressive phase change.
