โœฆ Synopsis

An experimental study of plasticity-creep interaction effects is reported. The combined stress tests are performed on thin wall tubular specimens of SUS 304 stainless steel at room temperature and high temperature (600" C). The plastic behaviors subsequent to creep pre-strain and creep behaviors subsequent to plastic pre-strain are obtained for loading along straight stress paths with a comer. The inelastic behaviors including both plastic and creep deformations are experimentally investigated. The interaction effects between plastic and creep deformations are quantitatively estimated with the equi-plastic strain surface.

The coupled effect and the anisotropic feature of plastic damage and creep damage in Nimonic 80A are analysed with special emphasis on the finite deformation and the material spin of the damaged material. In view of that both the plastic and the creep damage are governed by the formation of grain bo
