STRESS STRAIN RELATIONS FOR STRAIN RATE SENSITIVE ELASTIC PLASTIC MATERIALS.
Rept. no. 1,
STANFORD UNIV CALIF DIV OF ENGINEERING MECHANICS
Pagination or Media Count:
Extensions of the Sokolovsky Prikl. Mat. Mekh. 12261-280 1948-Malvern Jour. of Appl. Mech. 18203-208 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
