✦ Synopsis

Recent experiments reported in [1] show that for a boron-aluminium fibre-reinforced composite plastic yielding is effectively independent of tension in the fibre direction over a wide range of values of this tension. This confirms a long-standing conjecture by the author and colleagues. The results have major implications for the formulation of plasticity theories for fibre-reinforced materials. This paper reviews the theory of anisotropic plasticity based on the usual assumptions of plasticity theory, together with the property that yielding is not affected by a superposed tension in the fibre direction. Yield conditions, flow rules and hardening rules are formulated for uniaxial reinforcement; brief consideration is given to a material reinforced by two families of fibres.
