Plane Bifurcation of a Fiber-Reinforced Body with a Singular a- or n-Curve

抄録

Plane bifurcations from a finite deformation of an ideal fiber-reinforced body in which a singular a- or n-curve appears are considered. The relation between incremental stresses and incremental strains was obtained from the constitutive equation of the ideal fiber-reinforced composites, and jump conditions across the singular-stress curves for the incremental plane deformations were derived from their equilibrium. Four simple bifurcation problems were solved and compared as application examples.
