On anisotropic creep

The creep rates of an anisotropic metal are characterised by a generalised creep stress, a generalised creep strain rate and a corresponding flow rule. Invariance rules lead to a generalised strain rate function which differs significantly from that previously proposed. The method is applied to a pr...

Zusammenfassung:The creep rates of an anisotropic metal are characterised by a generalised creep stress, a generalised creep strain rate and a corresponding flow rule. Invariance rules lead to a generalised strain rate function which differs significantly from that previously proposed. The method is applied to a pressurized thin cylinder of material having three orthogonal principal axes of anisotropy.
