STRESS STRAIN RELATIONS FOR STRAIN RATE SENSITIVE ELASTIC PLASTIC MATERIALS.

Abstract

Extensions of the Sokolovsky (Prikl. Mat. Mekh. 12:261-280 (1948))-Malvern (Jour. of Appl. Mech. 18:203-208 (1957)) theory of strain rate dependent plasticity are proposed. These extensions are based on concepts of strain dependent viscosity and of hereditary integral viscosity, and are based on both the linearly viscoplastic constitutive equation and on the exponentially viscoplastic one. The basic tests, creep, relaxation and constant strain rate, are examined and the application of the theories to wave propagation is discussed. (Author)
