The defining relations of some polymeric materials subject to nonlinear deformation

  • Published:
International Applied Mechanics Aims and scope

Abstract

The defining relations are formulated for high-strength (rigid) polymer materials whose deformability is considerably lower than in elastic materials. For these materials, the elastic stage of deformation is geometrically nonlinear. At the plastic stage, a yield plateua is absent, and a linear displacement up to fracture is present. The relations are constructed based on the experiments conducted by the authors; the consistency criteria, and the Il'yushin-Shevchenko geometric approach.
