Kujawski D.♦, Mróz Z., A viscoplastic material model and its application to cyclic loading,
ACTA MECHANICA, ISSN: 0001-5970, DOI: 10.1007/BF01214633, Vol.36, No.3, pp.213-230, 1980 Streszczenie:
A kinematic hardening model is generalized by introducing plastic and viscous residual “back” stresses α, β that govern the translation of the yield surface. The evolution equations for α and β are proposed and the material functions are identified for a construction steel by carrying out tension-compression tests at different strain rates. The cyclic tests with changing strain amplitudes and frequencies are next carried out and model predictions are compared with experimental results. Afiliacje autorów:
