Abstract:

A constitutive theory is discussed for materials which undergo microstructural changes, and thus have different micromechanisms for the generation of stress in different regimes of response. Of particular interest is a two-network theory of polymer response in which, at some state of deformation, molecular cross-links are broken and then reformed in a new reference state. The mechanical response then depends on the deformation of both the remaining portion of the original material and the newly formed one. A particular constitutive equation is introduced in order to develop the methodology for performing calculations, and to study material behavior. The original and newly formed material are both treated as incompressible isotropic nonlinear neo-Hookean elastic materials, but with different reference configurations. Several homogeneous deformations are analyzed, and permanent set on release of load is calculated. Nonhomogeneous deformations are studied by means of the problem of the combined extension and torsion of a circular cylinder. Unloading and loading response is determined, as well as permanent set on release of load.
