Loading conditions in the local strains theory

Use of the local strains theory 7, 8] makes it possible to extend the loading criterion to complex loading paths if the hardening conditions are related to the local strains on individual small areas. Then the components of the total plastic strain increment are determined by integration over only those local areas on which the given loading condition is satisfied 9]. It is shown that the components of the strain tensor depend significantly on the loading history and the loading condition employed. The changes in the loading zones on the unit sphere are investigated for particular cases of complex loading as a function of the various loading conditions and the loading parameter.Mekhanika Polimerov, Vol. 3, no. 1, pp. 29–34, 1967
